So me and my bf were fooling around (we have not having penetrative sex yet though) I don’t think any cum got near my vagina.. and I did get my period but it was lighter then normal it lasted the same amount of time but just lighter. Well now I’m supposed to start my next period 8in 2days and I’m not getting all my usual pms symptoms, I’m getting sore boobs and mood swings and bloating. Could I be pregnant??
