hey mommas... do contractions sting? when i was under observation last week for my preterm labor contractions, they didnt hurt but were uncomfortable and now im feeling some stinging and slight cramping with the contractions as they come and go. im taking my bp meds but i kinda wanna wait until i see my OB in morning before making a big fuss.
