Brown discharge 33 1/2 weeks

Ashley

Hi ladies I’m pregnant with my second and he’s very big, I have extra fluid in my belly as well if that makes a difference. Well I went to wipe today around 11:30am(Wednesday) and it was brown, not thick at all though. Now I did have sex on Monday night around 9pm. It’s been more than 24 hours do you think this is what it’s from? I go to the Doctors in two days, should I mention it?
