Chiropractor- uneven pelvis

[Countrylife]

I've always had a bad back and dont have the best posture however since being pregnant it's gotten 10x worse, saw my midwife today and she felt around and told me my pelvis is out of alignment and I may need physio and recommended pilates.
Has anyone been to a chiropractor with a problem like this while pregnant? I'm in constant pain walking around, lying down etc only time it goes away is swimming and i cant be in the pool 24/7
I just cant seem to find relief
