I have been diagnosed with PCOS. The Dr started me on letrozole cd 3-7 to help mature the egg. I’m anxious to get a BFP this month and didn’t want to miss ovulation so I started testing on CD 5 when my period ended. CD 5 barely had a line then CD 6/7 the line was extremely dark. Then after it dropped. Based on glow I should have ovulated today but the OPKs lines get dark but I don’t feel like they are dark enough. Is it even possible to ovulate on CD 6 right after a period ends? It’s hard for me to know as I don’t have regular period. Or is it just due to the medicine?
