Need help ASAP I’m not sure if I’m pregnant and I need reassurance

letty

Okay, so I had sex around January 6 but I got my period around the 18 of Jan- 24th well at least I hope it was my period. However, on February I end up not getting my period at all and I’m starting to get worried mostly since there’s only 2 more weeks of March left and I haven’t got my period yet..
