Pms? Or more?

I have been waking up around 3:30 every night almost for the past three weeks. I just got my period about a week and 1/2 ago, but have had sex a couple times in the last few weeks. I’m not on B/C for medical reasons, but he always wears a condom and will pull out. I’m not too worried about being pregnant, but why am I constantly waking up? Along with that I feel like my hormones are everywhere lately, any advice would help.
