25 weeks pregnant.

My partner and I had sex yesterday. And after that, I had braxton hicks last night for about two hours.. But this morning, it went away. But when I checked my underwear this afternoon, I had a snotty discharge. It this my mucus plug? Or is this just cervical mucus? Help me out. The one one my underwear has a brown stinge in it. The one from my vagina when I washed was like clear jelly. But it’s just a small amount. Help.
