37 weeks - 1st timer

Hi Mummies, I had met my gynae earlier today, and she had checked my cervix dilation and was told 2 - 3cm..i was given a plan to induce when Im 38 weeks as baby has some complication. She also mentioned that my baby looks compact (when she measure and felt my tummy, not sure whats that mean, probably no space for the baby I guess!) As I was nervous thinking about all these, i forgotten to ask doc some question like mucus plug etc. So on my way to taxi cab, i already felt pain below tummy area and back pain when walking..probably cause of my big bod and the weight I carried, just my guessing.. Reached home, went to toilet and saw a blood at my pad. Not sure if it is consider mucus plug or just a one time blood after the doc check. Should i wait till I had contraction? Or went down to hosp back? Thanks alot!
