OK so I got a + opk on jan 23rd (unsure of when I started this cycle) BD on the 23rd and 25th and assume I ovulated on the 25th as I had ewcm and cramps on my right side. Well ever since 1 dpo (assumption) I have had weird bleeding. I spotted light brown for the first two day then I had a light flow of dark red almost black blood. This continued for the next two days an now I'm spotting again but its still dark red.. also I'm bbt charting and I had a temp dip from 97.7 to 96.6 this morning. Saw my doc at 3dpo when the bleeding started heavier as I was woried and she said it was just my period and did some swabs and a pregnancy test (negative). I didn't think it would be positive as its so soon after ovulation. Also having some symptoms of pregnancy including fatigue, nausea, fullness in the bust area but no tenderness and increased appetite. I'm totally confused can anyone help shed some light as I'm pretty sure it can't be my period so soon after ovulation?
