Birth control & plan b

I started birth control on February 2nd on day 3 I was experiencing light cramps . But on February 6 I had protected & unprotected sex barely. He pulled out way before he ejaculated . So i ended up taking a plan b on day 6 & also continued my birthcontrol. It’s been a week now on the pill .

Right now I’m still having stabbing pains on one side & in my boob . And a sharp pain i guess going through my uterus & i wanted to know if it was normal... or am i stressing myself out ...
