I got my period! But I feel PREGNANT...?

Okay so here's the story. My hubby and I have been ttc for 1 1/2 year now and nothing, but this month my period was 3 days late and it was normal. My question is could I be pregnant cause my tummy hurts like you know when you do sit ups and the pain the next day? Now my boobs don't hurt but I have been getting sharp pains once and a while and I do feel nauseated some times. I know I should take a HPT but i'm just not in a rush to get a FAST NEGATIVE I guess I want a SLOW YES LOL...I am getting tired of getting bad news every month. Can any of you ladies please help me in any advice I just want to vent to someone...Thanks in advance.
