Girls, hello. 17 weeks, my lower back on the left side is really hurting. In my first pregnancy, I had similar pains, but they were temporary, sometimes I would have them, sometimes not. But this time it's constant pain, probably for two months now. During the day with household chores it's not that noticeable, but in the evening the pain gets worse. I can't sleep at night. And it's not even such a big term yet. What will I do in the third trimester, I don't even know. Can anyone give me advice, or maybe there are massage therapists in Alma or Karaganda who could help?
