Hi, this is my first pregnancy and im 36 weeks pregnant and 3cm dialated , I ve been having contractions that are 8 mins apart, sharp period cramps and back pain sharp pain inside my vagina, i felt inside my vagina and i could feel the babys head through the sac. i went to the hospital, they told me i was to happy and wasn t in enough pain to be in labour and sent me home, could this be real labour or false?
