Waiting😬

So last Friday I had sex with my boyfriend and since then ive been concerned. At first i was having alot of clear discharge because i was ovulating all last week i believe. Now since Wednesday my discharge has been pink and my next period is in 6 days all these are new to me being the fact im an irregular bleeder Im 17 and theres alot of things that could be causing this but im scared its pregnancy. So ive been having a super anount of anxiety and stressing out of this world
