No pic but still TMI

Hey everyone, I am 13+2 and I have noticed an increase in my vaginal discharge. I mean, ever since I got pregnant, I've been pretty wet down there but for the past 2 days, it has been very "mucousy" and also large in size. I am afraid what if it's my mucous plug. I've had sex 2 nights ago and I organsmed pretty hard and it's been happening since. Is anyone else experiencing this?? also having cramps here and there.. nothing serious or consistent.
