<human>: Hi everyone, 

Not quite sure if this is where to post this, but I'm terrified right now. My girlfriend told me before I left school (we're commuters at a local university) that she had an early period and she was bummed since we couldn't have sex tonight on my birthday. She was upset because she was embarrassed, but I'm upset because I'm worried it might not have been a period.

We were both virgins until last week. We had sex Thursday night, but we stopped before I ejaculated because it became too painful for her. However, she didn't bleed very much, if at all (she wasn't quite clear about that part). Saturday night we had sex again, and it was great for both of us. Then Sunday we spent much of the day together and wound up having sex four times. Each time we used a condom, but she's not on the pill (she couldn't get an appointment with her doctor until June, and she didn't want to wait that long for sex). 

After she told me she had gotten an early period (far too early; I don't think she'd be due to have it for another two weeks, maybe two and a half), I immediately looked it up. I saw that sometimes implantation bleeding is mistaken for a period, and ever since I haven't been able to settle myself down. Now, it says that implantation bleeding normally starts 6-12 days after sex, not between 2-5 days. So that makes me feel slightly better, but I'm still worried. Also, my girlfriend said that she just realized her periods have been slightly irregular over these last few months, and I also read that some women notice a change in their cycles after having sex for the first time. I'm trying to stay calm, but I'm not gonna lie, I'm terrified. If anyone can give me advice, or put my mind at ease that'd be great— or if anyone thinks she's actually pregnant, then tell it to me straight I guess. 

Thanks for any help guys. Have a good one.

Can you condense the text into a few key points?
