ok little TMI. I am almost 30 weeks. my BH have been getting more uncomfortable as each week goes by. This morning around 2 am I noticed some spotting....not that much just little dots. that's normal for me this last two weeks. but also there was a glob of jelly like mucus the size of a nickel that came out as well. reminded me of ewcm when we were trying to conceive. would this be a bit of my mucus plug?
