*** long post sorry** So I may or may not be pregnant. Me and my boyfriend have not been trying but we aren't exactly being too careful either. It all started with breast tenderness but I didn't think too much of it. What did it for me was noticing my aerolas getting darker, a little nausea, heartburn and tmi but passing a lot of gas. But I tried not to think too much of it because I wasn't due to get my period for another two weeks and I thought It would be too early to get pregnancy symptoms. Finally a week later I started to take it more seriously so I purchased a first response test since it could tell me 6 days before my period. I go home to take it, I notice I'm bleeding. So I'm like great I got my period a week early I guess. So I don't even take the test. It only lasted two days and it was a really light period so I thought that was really weird. I also still continued to cramp after my "period" so I go to take a pregnancy test and I get a BFN. A few days later I'm still cramping and I notice clear discharge coming from my left nipple. At this point my nipples have darkened significantly, are puffy, and my veins are more prominent. I take a test and what seems like a BFN looks like a faint positive an hour later. So I take one more that night. Same thing. When I wake up it looks positive. I'm not supposed to get my actual period till this Sunday so I'm holding out on testing. But I feel pregnant and I'm a little excited of the possibility I just don't want to get my hopes up. I'm just wondering why would I get a positive an hour later as opposed to the alloted time ur supposed to take it? And do the tests look like evaporation lines or BFP? Two of them were faint and the next day I took the other one and it looks a little darker. I don't know if I'm going crazy.
