Had sex on the day that period was scheduled

I started having period cramps on Wednesday & they got worse on Thursday and everytime it feels that way, my period ends up coming. It’s been super accurate the past few months. I’ve even gotten it 3 or 2 days earlier than usual. So my boyfriend & I had unprotected sex about 3 weeks ago, & we had sex thursday (day my period was scheduled) & now I haven’t gotten it. I’m not getting cramps, but my whole abdomen feels some sort of discomfort. Even on both sides of my stomach. Have any of you ever gone through this or am I overthinking it?
