Back pains....

Kayla

Had Braxton Hicks during 2nd trimester for just a couple days. Now at 34wks+6days I’m having a pain strictly in my back that sometimes moves mid-back to lower. But last time it would move from my lower back to front lower abdomen and doesn’t seem to have a pattern. This is 1st pregnancy...should I start call doc tomorrow if back pain is still going or think this is just a warm-up for what’s to come?
