Here's a little background first so this makes more sense:
I'll be 22 in a couple of months, but when I was 14, I was sexually assaulted by my brother in law. Since then, I've had a huge issue trusting guys (I have gone to a psychologist and that actually really has helped a lot), especially when it came to sex. I could just never really bring myself to go all the way with a guy just because of my BIL. Anyway, my current boyfriend has been really understanding of the whole thing and we actually ended up having sex for the first time on May 5 and again on May 7 or 8 or so. We used a condom both times, and it definitely didn't break or anything like that because we totally would've noticed. The condom slipped just a tiny bit during sex, but definitely not enough to cause worry. I was in a lot of pain, so my boyfriend didn't even ejaculate either time -- I wanted him to stop, and he did.
However, there's just a little part of me that worries about pregnancy. I know I shouldn't because we were careful, but I still worry. I honestly think it's due to the fact that I was just overwhelmed by the whole experience and there was still part of me that was freaked out about the sexual assault and all that. Even so, I had my period start on May 12 (about 3-4 days early), but it started out as just brown spotting that day. The next day there was red blood, but it was lighter than normal. Bleeding picked up a day or two after that, and then I had brown blood on Thursday and Friday. So, my period was slightly lighter than normal in terms of flow, but not length. I was freaked out at first that it might have been implantation bleeding, but there's no way implantation bleeding would last that long, right?
I've been a little tired this week, but it's also been a stressful week for me. I just finished my finals for college on Wednesday. I slept over my boyfriend's that night, but I didn't sleep well after 2am (we fell asleep around 11) due to severe ankle pain (I just had surgery in February and may need another one this fall due to issues I've been having with my tendons that stabilize my ankle). I fell asleep early last night, around 11pm, and didn't get out of bed until 8am (I woke up around 7ish). I'm not sure if that's partly just because it was my first full day of summer and I didn't want to get out of bed right away, or because I didn't sleep well at my boyfriend's, or a combination of things... but it still worried me.
My stomach is also slightly itchy. I'm sure that's really nothing, but of course as I'm freaking out about this, I can't help but notice everything. Finally, I've been slightly nauseous for the past week or so, but definitely not to the point that I would throw up or anything like that... just slightly nauseous where I sort of notice it when I eat. However, I also did have a rotated L3 vertebrae and a rotated vertebrae in my neck (C2 or C4, if I remember correctly), but I went to the chiropractor Wednesday and I'm feeling much better now. I also have IBS, and I think I've been having a flare up, so I started back on Citrucel and I'm feeling much better from that as well. My low back has been sore for a while now, but that's feeling at least a little bit better since I went to the chiropractor.
So, I honestly think I'm worrying about absolutely nothing, so I think I'm just looking for some reassurance that I'm not pregnant. I really don't think I am, but I can't help but overanalyze the situation after everything that's gone on. Do I have anything to worry about?
** also, I should mention for those of you that suggest it: I can't be on the birth control pill due to a heart condition. I also have hyperthyroidism, so having periods a little bit early isn't entirely unusual for me (I think my period for April came like, 6 days early if I remember correctly).
