Warning some of this may be a tad tmi.

So I miscarried a few years ago when I was 18 and since then I've been very nervous about the idea of miscarrying again. Right now I'm 12 weeks pregnant and my fiancé and I are thrilled. Today we just had sex and when we were finished there was blood, and a decent amount of it and it was bright red... but there's been no pain, I had a shower and I don't think I'm bleeding anymore. I'm just really scared. I'm sure I'm fine if I'm not bleeding anymore it's just horrifying. I don't know what to do. Should I be worried? I'm probably fine right? Fuck I'm just freaking out.
