Yesterday I started a light pink spotting. It only was when i wiped. Now this morning it is heavy enough to need a pad or tampon. It is dark brown. I should add last night it stopped completely and when I woke up this morning it's heavier. My last period was January 28th to January 31st. Usually my period is 5 days. But it was 4 that time. I supposedly ovulated on the 13th of February. I say supposedly because I had all ovulation symptoms and tests show positive. Then 2 days later im bleeding. Any idea what the f is going on?
