Could I be pregnant?


Okay so I need help you guys. So my period was suppose to come on December 13th, and it still has not come on yet. I took a pregnancy test on the 16th and it came back negative BUT still no period. I did have sex with my ex during my fertile window and unfortunately he did ejaculate inside of me. My nips have been tingling like crazy, cramping real bad, and a lot of TMI symptoms that I don’t want to mention. Could I be pregnant or just worrying myself?
