Please Answer Soon As Possible

I was on the pill for like 4 months then I stopped, like a month ago I found a month packet left and I started again by myself. I used the pills like I should and then started having unprotected sex. When I got to the poin on my pills where I was saposed to have my period I didnt get it... I dont have any other pregnancy symptoms but the skipped period. Is it possible that I just skipped my period for sum reason? Or am I pregnany... Im so scared... (but I was on the pilll.....) (this is a repeat message of "ahhh I need answers" but im stressing out! )
