I haven't started my period its been 4 days yes I'm sexual active , this was the first time in 8 months but when we had sex it was only like 10 mins due to hungry ass friends 🙄 & he never came he ended up handling that in the shower but the morning after I ended up on my period Now before you say "go take a pregnancy test just incase" listen to this

so ive been home for a month and in this month I haven't Really slept as in up all night dont fall asleep till 5 maybe 6 in the morning , then waking up at 9 and being up all day and night . since I've been doing that I haven't been feeling well either so my thing is could my period be late because of lack of sleep or pregnancy or could it be because of just starting to have sex again
