Pregnant? Help pls

Prisci

I was supposed to get my period a week after I had sex. It has been 2 weeks since I had sex and I still haven’t gotten my period. I took a test yesterday and it came out negative. It’s also been one week since my period was supposed to arrive. The thing is I feel like my period could come at any time but I’ve had this feeling for a week now and nothing. Can anyone help or has anything happened related to this.
