I see numberous posts online and not all get answered.

Well heres mine... Me and my boyfriend BD on 12-24 and 12-28. I have middlesmertz and I believe I ovulated on the 30th or the 31st. I get severe pain before I ovulate. Now I am not saying I am 100% sure that I did on those dates. On 1-9 which I believe was 10dpo I started bleeding but very lightly and only when I wipe TMI sorry and it lasted until today 1-12. I didnt have my normal abdominal cramping and I have been feeling bloated which is definately a period symptom. I have been soo nauseous and I know that it could be my mind playing tricks on me. I usually bleed heavy and with clots and I know that our cycles change every couple of years.
My question is do you think it could be implantation. I POAS today and it was BFN. We are trying to conceive and I just dont want to get my hopes up.

I have heard women say that they didnt BFN until 14-16 days sometimes. Any advice would help.
