What Is Follicle Tracking?
Follicle tracking also called follicular monitoring or ovulation tracking is a series of pelvic ultrasound scans performed during the menstrual cycle.
The scans monitor:
-
The number of developing follicles -
The size of each relevant follicle
-
The development of a dominant follicle
-
Changes in the ovaries during the cycle
-
The thickness and appearance of the endometrial lining
-
Ultrasound findings that may be consistent with recent ovulation
Follicle tracking can help identify how follicles are developing and support decisions about the timing of intercourse, fertility investigations or treatment directed by a fertility specialist.
A single scan provides information about one point in the cycle. A series of scans shows how the follicles and endometrial lining change over time.
Follicle Tracking Available Seven Days a Week
The timing of follicle tracking scans depends on how your ovaries respond during your menstrual cycle.
Follow-up scans may be required at short notice or only one to three days after the previous examination. Restricting appointments to particular weekdays can make effectivep>monitoring difficult.
The Blackheath Clinic offers follicle tracking seven days a week, allowing appointments to be arranged according to your cycle and scan findings.
This may be particularly useful if you:
-
Need several scans within one cycle
-
Require a weekend appointment
-
Have been given specific monitoring dates
-
Are travelling to a central London fertility clinic
-
Need monitoring requested by an external fertility specialist
-
Have irregular or unpredictable cycle timing

What Does Each Scan Assess?
Each follicle tracking scan may assess:
When Should Follicle Tracking Begin?
The appropriate starting day depends on:
-
Your usual cycle length
-
Whether your cycles are regular
-
The purpose of monitoring
-
Whether medication is being used
-
Previous scan findings
-
Instructions from your fertility specialist
For a typical natural cycle, the first scan may be arranged around day 8 to day 10. Patients with shorter cycles may need to begin earlier, while those with longer cycles may start later.
If another fertility clinic has given you specific instructions, these should take priority
Our team can help plan the initial appointment based on your cycle dates and the reason for monitoring
How Frequently Are Scans Required?
Follow-up scans are commonly performed every one to three days, depending on:
-
Follicle size
-
The rate of follicular growth
-
Endometrial development
-
The anticipated timing of ovulation
-
Fertility-clinic instructions
-
Medication being used
Some patients may need only one or two scans. Others may need three or more.
Our seven-day availability allows subsequent appointments to be arranged according to your scan findings rather than being restricted to particular weekdays.
Our Patient Review
I was understandably very worried and was able to book an appointment within just a couple of hours. From the moment we met him, Dr Mac Sweeney was kind, reassuring, professional and genuinely caring. He took the time to listen, explained everything clearly, and made us feel that my husband was in very safe hands.
What impressed me most was that his care did not stop when we left the consultation. He followed up on several occasions to check on my husband's progress, prescribed more medicine and even went out of his way to provide a letter for our insurance company, which was incredibly helpful.
In a world where good service can sometimes feel hard to find, Dr Mac Sweeney demonstrated a level of compassion and personal attention that was truly exceptional. The fee was also very reasonable, especially given the time, care and support we received.
I would wholeheartedly recommend Dr Mac Sweeney to anyone needing medical assistance and will always be grateful for the kindness he showed to both of us. If I lived in London I would most certainly subscribe to his membership scheme so he could deal with all my family's medical needs.
The clinic has a friendly and relaxed atmosphere, with a fresh, calming scent that immediately creates a welcoming environment. Everything was explained clearly and professionally, making the whole experience completely stress-free.
I particularly appreciated the expert advice and felt comfortable throughout. I would highly recommend The Blackheath Clinic to anyone looking for a professional, patient-focused service.
As I entered the tastefully curated space, I encountered one of the rarest of things: a polite, smiling and genuinely welcoming receptionist. In fact, she was so warm and courteous that I briefly wondered whether I had wandered into an upmarket spa by mistake.
Then I met Dr Sweeney. He was charming, courteous, friendly and thoroughly professional, with the kind of bedside manner that reminds you what general practice can be at its best: attentive, humane and quietly confident. He came across as someone who takes real pride in his work and genuinely cares for his patients.
The whole experience felt like stepping back into a time when patients were warmly received and doctors truly doctored. As I was leaving, Dr Sweeney mentioned that he was off on a home visit. A GP doing a home visit in 2026? I was so astonished I nearly needed examining all over again.
Join this practice quickly before word gets out and the list fills up. This is care delivered by people who genuinely care, and that feels all too rare these days
I had lip filler and RRS Long Lasting skin boosters, and she took the time to explain everything clearly, answer all my questions, and ensure I felt confident about the treatments. Her attention to detail and gentle approach really stood out, and I couldn’t be happier with the results.
Dr Micha Plugaru truly combines expertise with a warm, personal touch. I would highly recommend her to anyone considering aesthetic treatments — you’re in the safest and most caring hands.
Can You Perform Monitoring Requested by Another Fertility Clinic?
Yes. We can provide local ultrasound monitoring for patients receiving care from another fertility clinic.
Please bring or send us:
-

-
The required scan dates or cycle days
-
Details of the measurements requested
-
Relevant medication information
-
Contact details for your treating clinic

Can Follicle Tracking Help With Natural Conception?
Follicle tracking can provide information about follicular development and the likely timing of ovulation.
This may help patients understand their cycle and plan intercourse around the probable fertile window.
However, follicle tracking cannot guarantee conception. Pregnancy also depends on factors including:
-
Egg quality
-
Sperm quality
-
Fallopian-tube health
-
Fertilisation
-
Embryo development
-
Implantation
-
Age
-
Other medical and reproductive factors
Patients experiencing difficulty conceiving may require a broader fertility assessment.
When Should I Consider a Broader Fertility Assessment?
Follicle tracking focuses on what is happening during one menstrual cycle.
A broader assessment may be appropriate if you:
-
Have been trying to conceive without success
-
Have irregular or absent periods
-
Have concerns about ovarian reserve
-
Have experienced recurrent pregnancy loss
-
Have a history of pelvic infection
-
Have had previous pelvic or ovarian surgery
-
Have symptoms suggesting PCOS or endometriosis
-
Have not had semen analysis performed for your partner
-
Want a more complete review before continuing cycle tracking
Our wider fertility services include:
-
Doctor-led AMH assessment
-
Antral follicle count scan
-
Combined ovarian reserve assessment
-
Fertility hormone blood testing
-
Pelvic fertility ultrasound
-
Comprehensive fertility assessment
