You prostitute!
No i'm just kidding ahaha.
I dont know if your pregnant, but I can tell you that symptoms don't come as soon as a week or whatever after you have sex, which is what girls dont seem to understand.
I started getting symptoms 8 weeks after my missed period, which was my boobs hurting, then a week after my morning sickness started. My stomach didnt even start to get hard until I was 5 months. It is different for everyone but you do not get symptoms just after days or a week after you have sex.
