Period came 2 weeks early?!

Jewelesa

Heyyyyy 👋 So my husband and I had sex on our wedding night which was also the 3rd day of my period. First, let me say it sucks having your period on your wedding day

ANYWAYS....my next period came 2 weeks early! What could've caused this? My cycle between periods are normally 28-31 days. I'm not on any form of BC, haven't changed anything in my diet or routine. Obviously he came in me, but I'm pretty sure there's no chance I could be pregnant since I've gotten my period...right? Please someone give me their insight on this
