I'm currently in bed with my maternity pillow with the most uncomfortable feeling in my lower back and by my pelvic bone. Like baby is right in there tapping her head against my bone, also feeling the need to poop more eeek tmi sorry. I have been losing my mucus plug all week and have only started to really feel heavy and helpless! I work from 8am to 5pm weekdays but I'm only in administration so not super busy only my brain (which is equally as horrible as I have major baby brain) anyway has anyone else felt this? Is it a sign I'm popping out a baby sometime soon?!? I'm impatiently waiting for my baby girl!!! Ftm so tips and advice would be amazing!
