spotting? help?

My boyfriend and I had unprotected sex two weeks ago, about a week after I got off my period. He didn’t finish inside and he pulled out, but to ease my mind I took a morning after pill within 24 hours anyway. I felt the side effects for a few days and then was fine, and then had protected sex with a condom a few times a week ago. When he pulled out with the condom on he said a little cum got on the outside (not inside) of my vagina and I washed it off immediately but felt really nervous.

My period is due in the next week and I have had some light dark brown spotting the past couple days, as well as what I think are some other fairly typical PMS symptoms, but I’m SUPER worried. I know the morning after pill can mess up your cycle as well as cause spotting, but I’m stressing so much it’s making me impossibly anxious.

Any advice?? I know I need to be more careful from now on because I’m definitely NOT ready for a baby. Just in desperate need of some helpful and calming words!
