I'm due between 4/28 and 4/30, (was given different edd based on lmp and size of bb. 1st week of July 8 &9 to be exact I had sex with one partner. Had a full blown period 7/23 very heavy, I went thru several pads and every thing. Had sex with another partner 7/27, 8/6 and 8/8. I tested for pregancy around 8/13 and got a negative just in case I thought... Was due for my period 8/23 or 8/24 and got a bfp on 8/23. I'm almost 100% that the baby is partner #2's but that little smidge of doubt is so stressful. What does everyone think? Should I be fine since I had a period and negative test 1 month plus after 1st partner or is it possible....
