beige discharge?

I am 37 w + 2 days pregnant. My SO and I just had really rough, deep penetrating sex. Afterwards, I went to the bathroom to clean up and pee then I wiped and didn't see anything besides discharge/cum. After I emptied out my bladder, I had some trickles of fluid then it stopped. I looked in the toilet paper in the toilet before I flushed and noticed that there was a very tan beige color discharge on the toilet paper. I've looked it up on google and can't find anything.
