Should I be worried ?

Me and a friend had sex for 2 weeks, every other day then it was everyday leading up to ovulation. He came in me 5 times (estimate ),we never used a condom because he would tell me not worry about it because he had SCD.

Update: I started spotting today, started off a dark red mixed with discharge. It stopped after I took a shower and took a nap but started again a light watery red.

1/18/19 Update: took a couple tests and they all came back negative even the blood test, I don’t know if those 3 day (28-31) was my period because my period is never usually light and that short. Waiting for next week to see if I get my period.
