Hi, I finished my second round of clomid (100mg). On CD 13 I had follicle scan I had two follicles one on each ovary(14.5 and 18mm). My question is that my doctor said I would ovulate the next day. I take my bbt every morning and I haven t seen a spike in temp. I did see a slight spike on CD 20. Is it possible that I can conceive on day 20 or will my follicles be too largaye?
Hi, The BBT test is not a very sensitive test to find out the ovulation. If the follicle was 18 mm it would have ruptured the day after or may be 1 day after. So even if you have tried on the same day or any of the days after scanning, you may conceive, because sperms can fertilize the egg within 72 hours and an egg is viable for 24 hours. Day 20 will be too late. So there will be little chance to conceive. Hope I have answered your query. Let me know if I can assist you further.
