I was on letrozole 5mg from CD3-7. I had ovulated on CD10 confirmed through scan. From 1 dpo - 6 dpo I had brown liquid discharge only while wiping. From 6-8 dpo I had brown and red liquid discharge. From 9-11 dpo I had a stretchy clear discharge with a tinge of blood in it. Today is 19 dpo and I still have not gotten my periods. I sometimes get white sticky discharge these two days, very little of it. And I am very anxious to do a pregnancy test. What can cause delayed periods after ovulation? Are there any chances of pregnancy this cycle? I have no symptoms whatsoever.
