I am having low back pain that comes & goes along with a headache. I have had loose stools for over 36 hours. & I wiped pink mucus plug piece last night went & got checked my OB at 11 am she said there is blood in my vagina but my cervix is still closed. I have been taking Imodium for my loose stools. I took Tylenol & used a heating pad but I am still feeling the low back pain & headache. Im 32 weeks pregnant.
