What do you guys think ?? Emergency pill + Period

Hey guys. Before starting the story i would like you guys to know that in November I didn’t get my period. I think it was because i was under stress with getting everything for my vacation. ( Got it on vacay the day I went to visit my bf December 18) So I went on vacation this December. On December 26 I had unprotected sex with my boyfriend.he pulled out but I think it wasn’t on time so I decided to take emergency pill. Got my period few days later. Then had sex with my bf again January 9 at the beginning we did it unprotected and then he put a condom on. Decided to take the emergency pill again cause I didn’t want to risk getting pregnant. Yesterday I got my period again. Which means I’ve gotten my period 3 times in a month. I’m super scared because I’ve heated taking that pill a lot of times is not good. Just want your guys opinions about all of this.
