I'm 35+3 and had a growth scan today, twin 1 hasn't grown as much as doctor would like so I was given the first steroid injection. I've now been awake the last 3 hours having what I assume are Braxton Hicks. They aren't regular but are still pretty close and uncomfortable enough to keep me awake.

Is this a side effect of the steroid injection? Or could something be happening?

I'll definitely ring my MW in the morning if still happening and I have to go back to hospital for the 2nd injection anyway.
