Stopping the pill and next period!? Help!!

I stopped taking my birth control a month ago. Just decided to switch it up as this one was giving me problems. I've been perfectly regular for over two years (one year on birth control) and now I'm 3 days over due ... Not sure if this is normal or not. I was at the doctor last Monday and the urine test was negative but I wasn't actually due for my period until Thursday! Now it's Sunday and still nothing. I do get slight pinching and little cramps but no period. I haven't taken another test as I'm just waiting it out... Any advice!?! I am sexually active and was just after my last period stopped..
