Can you get chiropractics while in early pregnancy?

I'm sorry if this is "dumb" question. I just don't know 😳🤷🏻‍♀️

I really thought about posting this question for a few days just because people have been so critical on here lately...

Im nine weeks pregnant. This is my first successful pregnancy this far. Anyways, my back is KILLING me. I have a very physical job- which I've significantly decreased. But my lower back is killing me. It's hard to sit down at all. My only relief right now is laying flat. I've had chiropractics done previously (before pregnancy) that's helped significantly when my backs been "tweaked". Is it safe to get it done while early pregnant, as long as I let the chiropractor know before hand?
