??? Any insight

So i had a period that was delayed four days, and before my period I was having sex constantly. Aka trying to get pregnant! Then the first day of my late period, it was really light and start slow, then progressed but only lasted 4 days instead of 5. Now that’s it’s reeks after my period, I’m having more discharge then I ever had. Milky white, no Oder, infections etc… stomach hurts with cramps on back. I also feel nauseated, and vagina looks swollen, same color doesn’t hurt, just more big I guess??? … what is this? I never experienced this before
