Brown discharge

Rachel

Okay so tomorrow I'll be 9 weeks and my partner and I had sex last night and we've had it pretty normally but tonight I went to the bathroom because I could feel what I thought was just normal discharge and when I wiped there was a lot of brown discharge and I haven't experienced this before. I have some pain on my right side where I usually do when I'm ovulating! What could this be? It's freaking me out because I'm a first time mom! Could it be from the sex??
