am I pregnant?! missed period by 10 days

hey girls, sooo about two weeks ago tomorrow Im pretty sure my boyfriend and I had sex. protected. no big deal wasn't the first time BUT I was expecting my period last Tuesday and it still hasn't come?! yesterday and today I've had pretty bad cramps like I've got my period but no sign of blood. the first few days after it was supposed to come I had quite a bit of discharge but that stopped for a day or so and now it's lessened and there's still a bit but not the point where I need to have like a panty liner on. IDK whats going on? pretty certain I couldnt be pregnant cos we were safe but you never know. would you be able to feel if the condom split? surely you could feel him cumming in you if it split but I didn't so assuming it didn't split. soo yeah had cramps bit of discharge and I've also been eating HEAPS like an abnormal amount for me which doesn't usual happen on my period-i eat more but not this much more... also my periods neverreally this bad. first time I had sex it was late by maybe 5 or 6 days but it still came this is a lil more worrying. never been this late and it's rare it being irregular seeing as I've had it for like 5 years now (I'm 16) any advice would be super helpful ty! photo is of my current calendar Btw. had sex a couple days after ovulation window ended
