Bloating?!!...Help dont know?

I am in a weird predicament, i had my period and then got of BC , had a couple days after now I should have gotten my period today DIDNT, but i heard that its unnormal for a mo or two after getting off i dont know, ..... My stomach is so bloated its scary!!! I feel so full yesterday and today , been gy (sorry) and just have had weird twinges in lower stomach abdomen (not cramps) I dont have sore though, have headaches, ... I just dont know when i should test again but the stomach is the one that scares me because I can eat like 3 sandwiches and drink somes stuff and not feel this weird fullness (kinda almost tight like to capacity in my stomach) Whats going on is this preg signs? ..thanks
