FTM! someone please tell me what I'm feeling!

B

all day I've felt like baby gained like 10 lbs over night. like my belly just seems heavier/harder to carry. Ive been getting over a cold and every time I cough or move slightly or laugh I have a very uncomfortable pain feeling. I can't tell if this is pressure associated with early labor that so many women talk about. breathing deeply is helping a little. also I started losing my mucus plug 2 days ago but no water or leaking. I'm 34+5.
