Cramping?

Alex

FTM 37 W and 3 D. Ive been having BH for the past 3 weeks and lost my mucus plug 2 weeks ago. Today I've been having a lot of cramping (almost like I'm going to start my period) in my pelvis and around my tailbone. It hasn't been consistent but keeps getting more painful. Is this something to be excited about or a normal end of pregnancy symptom?
