so on saturday 8/3 i had sex on my period, the man orgasm inside me twice, i believe i might be pregnant but too early for a test to read because it hasn’t been week yet, my boobs are swollen and sore, my lower back is hurting i’m bloated this was the first symptoms with my son but didn’t know till i was 5 weeks, so i took a test it was negative, does that mean it’s too soon??
