FTM, could this be mucus plug??

So I went to the bathroom this morning. I tried pooping and couldn’t. Only peed. So when I wiped I noticed I had brownish/yellow mucus like discharge.

I have never seen that before even when I have pooped. This is the first time I’ve seen that. It wasn’t a lot but still there.

Idk if this could factor in but I also had sex last night so maybe it’s from that?? I have a doctors appointment tomorrow in any case.

Also, 32 weeks.
