WTF!!!

My husband and I just finished having sex and after I was cleaning up and wiped and literally looked like I shit myself... I wiped 4 times and each time I had brown stuff on the toilet paper. I wiped my actual butt and got what looked like a little poo. Kept wiping my vagina and it stopped. Did I seriously shit myself a little while having sex?! I didn’t feel like I had to poo but I’m soooo embarrassed but I don’t think my husband noticed!!! I asked him if he had any blood or brown dried up blood on him and he said no. Where is this brown stuff coming from?! Idk if it was shit or maybe brown discharge. Someone help!
