period has been weird..

so the second week of last month I had unprotected sex and i’m not on birth control. The day after i immediately took a plan b. Then after a week and a half i started having a brownish discharge for about a week then it stopped. After a few weeks of waiting on my period, i got something Saturday night that made me think it was my period, but i’m not exactly sure it was. It was a brown ish color again but then sometimes it would be mixed with just regular red blood.. and i really haven’t been feeling my usual beginning of period symptoms for it besides a little bit of acne, cramps, & fatigue. It stopped this morning so i’m really unsure as to whether this is normal for me to have since I took plan b or if i should get it checked out or if i should take a pregnancy test.

Anything helps ! Just super confused atm 🤧
