First off, I am not someone who pays attention to the dates of my periods, I only know around what time of the month it's due which is usually always the very end of the month or maybe the 1st or the 2nd. On June 25th, I had sex with my boyfriend and woke up the next morning with slight cramps and light blood only when I wiped, I assumed it was my period because it always starts off slow for me and I didn't realize until about 3 day's later that it never picked up and had stayed light and Brown for about 2 1/2-3 days. I googled it and came across implantation bleeding which sounded accurate because it indicated the symptoms and the fit the 6-12 day period after conceiving which is when we had sex prior, however Me and my boyfriend are extremely safe, we use a condom each time and he pulls out before. I'm sure there are still some odds but it seemed unlikely to me.. Waited a few days to see if I would get a heavier period (was unsure if the light one counted) I am what would be considered about 11-12 days late, took an early response pregnancy test two days ago and got 3 negatives, however I only waited for different parts of the day just to see if that would make a difference. I had sex again last night and immediately afterwards discovered blood and am still bleeding this morning (kind of light but def red blood) and am experiencing cramps. I did have sex another time between these last two instances and didn't have any bleeding afterwards. I have no nausea, appetite chances, lethargy or breast tenderness although I am very flat chested (not sure if that would make me less vulnerable for that lol) I am unsure of what to think right now and would just like anyone's opinion on what they think is going on and if they believe I could be pregnant. Thanks :)
