I had sex on two days ago. It was un protected and he pulled out. To be safe I went to the nearest store and bought a plan b one step pill. I have very very small cramps. Is it too early to get them?. I also rarely get my cycle. I haven't been on birth control pills since Februaryn and I only took them to have a regular cycle, but i stopped taking them until next dr visit i did receive a cycle in april. Should i be worried?
