Helpppp

So i lost my virginity about to two weeks ago and every time we have sex, we use condoms (except the one time he came in my mouth and I swallowed) but now my period is 4 days late and im properly FREAKING OUT. It could be because of stress ( problems at home ) or whatever but I just need reassurance or something. So please, help

Update: I GOT IT. BLESS AND THANK YOU
