Maybe this will help
From my experiance..
BH contractions usually happen when baby moves..
and then u get the tightening feeling you girls are saying u have..
and it can feel like pressure.. like baby is pushing on ur tummy ..
but they should be painless.. altho some women find it uncomphy and some even think there going into labor.. cuz it hurts to them
Real contracts
i felt it in my lower back, pelvic area and the pressure.. and pain where u have to breathe thru them
and they come regularly.. for me they come every 2-3 minutes.. sometimes less then that.. and they last for like 35 -45 seconds long.. thats why they kept me in the hospital..
if yuor contracts are irregular and not that painless or even if u have a bit of pain..
its probably my guess BH.. hang in there ladies..
and i hope i could help a lil.. BUT i suggest.. ahaha from experiance... call your doctor..
asap.. if your in pain.. and ur worried..You never know.. !!!
