Dear Dr Wisot

Thank you for always replying to my questions.

I had a day 21 scan today and only had 4-6 antra follicles counted.

Previously I have had day 2 scans for AFC and have had 8-10 but this time I had it done on day 21 and there was less. In all I have read about when to count AF, it says day 2-5.

So my question is - is a day 21 AFC accurate or is it likely that more AF's would appear by day 2 before stimulation starts?

Many thanks for your time.

Day 21 is not the best time to do an AFC. Very early in the cycle will give the most accurate estimate and that's subjective. AMH levels can help confirm the ovarian reserve and is more objective.
