Pregnant? Trich? Just abnormal? Help!!!

Kasi

My periods have been ALWAYS been abnormal. It makes it very hard to know when I'm ovulating between. My cycles is typically anywhere between 5 days of bleeding to 3 weeks of bleeding then off for 10 days to 4 weeks. Very unpredictable and I have given up trying to figure it out and there are almost no surprises anymore.

I've recently had dumb drunken unprotected sex (we usually use a condom but we were wayyyy too drunk) 3 days before when I thought my period would start. I thought it started fine (normal sporting at first and then normal bleeding) but then after one day it turned into foul smelling greenish-brown thick mucus with pink streaks. Now I'm not talking fishy smell, I'm talking rotten foul makes you gag smell. I use summers <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> to stay clean and rotate tampons and pads every few hours, but this mucus has been non-stop for almost 2 weeks. This has never happened. I'm worried I may be pregnant as that was the first time I've had unprotected sex and I'm not on birth control. I've also read about trichomoniasis but don't know much. Or maybe it's just another abnormal period? I'm really worried about this and would like to act asap to fix it so please help!
