No cramps?

I haven’t had really any real PMS besides nausea, bloat, headaches, acne, and mood swings. But i almost ALWAYS cramp before my period. I’m slightly panicking that i’m pregnant because I had sex with a condom on, but it slipped off mid-way but he hadn’t cum into me. The condom was still inside of me so we assumed any spermicide was caught into it anyways. My fertility rate was very very low and because it was pre-cum, we didn’t worry. Now I am worrying and am waiting for my period to come.
