Early labor?

Lindsay • married to a wonderful man, have 2 angel babies, and pregnant with our rainbow baby boy

Sorry long post ahead. So I'm 32 weeks and I'm a ftm so I have no idea what to expect as far as labor goes. So a couple days ago I had a lot of really bad braxton hicks but they eventually stopped and yesterday and today (tmi sorry) sometimes when I go to the bathroom my under wear is wet but it's not like the normal discharge iv been experiencing. And now this morning I'm feeling very crampy it feels like I'm going to start my period. Baby boy is still moving around like normal. I just need some advice. Should I call my Dr? I don't think iv lost my mucus plug or anything (can you even go into labor if that hasn't happened?) I just don't want to be that person that freaks out over every little twinge. Thanks in advance
