Pain lower left side - 37 weeks

[mistypop]

Hi all, I have a constant pain that gets better then worse again on my lower left side above pelvis. Since early this morning. Should I be worried about this or is it probably just normal stretching

I had similar and phoned my midwife department. They asked for a load of information before being brought in for a check.
I’d record the length you have the pain and time i between for an hour or so. They suggested I walk around to see if it eased, then rest if it didn’t. Also drink something cool.
