Is this normal coming off the pill?

I stopped the pill about a month and a half ago, and had a normal period in early July. This month me and my SO have only given eachother oral/handjobs until I get back on birth control. However... It's four days until my period and I feel pregnant! I'm having cramps in my lower abdomen, cheast and breast pains and nausea. I've never had PMS symptoms before a period, which is why I'm freaking out. Did anyone have else have these kind of scares after coming off of BC? I've already taken a test just in case, and will keep testing until I get a period...
