This is new to me

L

So ive been having unprotected sex with my boyfriend for 4 months now and ive never spotted after or anything and my period is normal and i already got my period this month so last night i moved in and when i was done putting stuff away at night night we had sex and after when i went to pee i saw blood on the paper when i wiped but nothing hurts i was getting slight cramps but nothing too drastic & again this morning i wiped and it was spotting again this has never happened before Can anybody help ?? Also we did decide we wanted a baby yesterday as well but ive been so stressed & the sex wasn’t rough usually he is but i never bleed and last night it was passionate and slow if it makes sense?? We also have started having sex on my period:/ if this is any help
