Hello Dr., I am planning for pregnancy. We used ovulation kit to check for ovulation and tried for pregnancy. I did the pregnancy test after 14days ovulation and it tested negative. My periods haven’t started yet after 37 days of my LMP. I have PCOS and my cycle is happening greater than 35 days. I heard that in PCOS, ovulation date gets affected and that’s why there is delay in periods and once ovulated periods come for sure after 15 days of ovulation. But my periods didn’t come even after 20 days of ovulation? Is it true or should I do pregnancy test again?
