Make sure u are staying hydrated too because that can cause contractions.
I Started Havinq Contractions At 28W, And My WHOLE Preqnancy I Had Severe Lower Back Pain.
I'm Now 36W And Ever Since I Started Contractions, My Dr Makes Me Go In Every Week To Be On The Monitor.
I Was Put On Bedrest At About 30W. Every Preqnancy Is Different, I Wish You Luck And That Everything's Good (;
Well turns out everything is OK, I just need to take it easy with work and rest as much as possible
Better safe then sorry ! Go to the hospital ..... Hope all is well !
