I had sex but I got my period (my period usually last for 6-7 days 🙄) and this time it only lasted for 3 and 2 weeks later I'm still having cramping along with dizziness, nausea, and I'm so tired. I don't have access to a pregnancy test, I'm 15 and go to a Catholic private school with very strict parents who always know where I am and I see no way of how I could get one. Is it possible even tho I had (think I had) a short period.
