My friend and I hooked up on my peak ovulation day, with no protection (he forgot a condom and didn't really pull out). I started taking tests (all FRER). I must have missed a line or something because one had two looking back on it later (I don't think it was evap - it was a FRER and the line seemed very normal - although there wasn't a ton of color). I then took a blue dye (kind of broke after the FRERs) and it came back positive - I took the test apart too. Another FRER was veeerry faintly positive. This was all at around 4 weeks. Too early and light for my very regular period, I had some brown bleeding but it lasted only three days and only needed a liner. Meanwhile I'm getting sick, tired, bloated beyond belief, my boobs kill, etc. then, I started bleeding again, at around seven weeks. It was again entirely brown, only required a liner, and was done in three days. I was worried, but my symptoms persisted (if even stronger) - peeing, almost puking, and my lower abdomen continued to bloat and grow - not in a soft, fat way, it was all hard (and I'm a stick so it's noticeable). I'm now supposed to be at 11 weeks. My mom gave me a digital test, but I'd peed right before (literally 15 min earlier). It came back negative. Yet I have the symptoms, and those other tests? What do you think, anyone who has been through this before? Am I pregnant or thinking too much? I don't have enough money for a new test. 

Meanwhile the potential father and I are on weird terms, everyone at school has found out (not of my doing) but thinks I'm faking to get attention, which leaves my friends in a tricky spot as they want to stand up for me but don't want to confirm anything. I realize this is a lot for one post but I could really use some help. Anything is appreciated.
