I had sex almost exactly a month ago with my boyfriend at the time. Unfortunately, the condom fell out and we didn't notice, so there was direct contact, but before ejaculation. Simply continuing to ejaculation with a fresh condom, we thought nothing of it. My period came today, a week late, and I'm not quite sure if it's implantation bleeding because it's the regular color, but not as much bleeding as usual. I just returned from a trip where there was intense hiking, and I've also been under a lot of stress this week, so I figured that this was accounting for the both the tardiness and the lighter bleeding. The past two days, I've been experiencing nausea, some fatigue and light headaches, which I normally don't have before periods. I also attributed this to the aforementioned outside factors.
Should I take a pregnancy test just to clear things up? It would be a bit of a hassle for me to attain, but I have ways if it's absolutely necessary.
I don't want to panic on such murky premises, but then again I also don't want to wake up one day with someone playing soccer with the inside of my stomach.
