Today would be 15DPO, my expected period was 8DPO-12DPO ( i ovulate late and have a 4 day period ) . i would be 7 days late today and usually only a day or 2 late . i got 2 faint positives on a pregnancy test 2 days ago and yesterday. i started spotting lastnight and than this morning i was excessively bleeding, and had blood clots . my periods are SUPER light so definitely different from my normal period .. can anyone tell me if i had a chemical pregnancy? whats your story or any advice ?
