Idk my body's weird

So me and my boyfriend had sex while I was ovulating and he's not sure if he came in me but it's two days later and I'm having Jelly like brown discharge along with just wet brown discharge? Idk what this could mean any advice on what it could be? PS IVE NEVER HAD THIS DISCHARGE BEFORE ON DURING OR WHEN MY PERIOD IS ENDING

Update: I keep cramping and peeing
