Confused and curious

Melissa
So my period was due yesterday and is very rarely more than a day late! It felt all day yest that it was comin any minute! Then last night we had intercourse and evertime we have had intercourse right when my period was on the verge of coming, my period came very soon after that! Well, this time all the feelings of my period coming have left! Today I don't really feel like it is coming! That is so different! So I took a test and it is negative! Not sure what to think, and I have lost one early before! Just dont want to take chances! Just want to know if it is still possible that I am pregnant!
