I have pcos. My 1st day was last april 23. I am trying to conceive and took letrozole on my 3rd mens day til the 7th (April 25-29). Had follicle usd on day 13 (May 5) but found out that there's already corpus luteum. This means the follicle has ruptured already, right?

My husband and I had unplanned contact last May 1 but was a quick one and I did not raise my legs for 30minutes. Also, had contact last May 3 but had some oral on that so I was afraid it might get the sperm killed (? As they say, just learned recently). On May 5, as advised by my OB to have the follicle scan but it showed that there's already a corpus luteum. My husband and I still had contact on May 6 and 8, just to keep the every other day advise in getting pregnant.

Do I have the chance? Had a miscarriage last december 30 and failed letrozole last month.
