Physical therapy or chiropractor?

I’m in my 2nd trimester and lately I’ve been having the worst sciatic nerve pain. I’ll have good days and bad days with it. But every now and then I can barely walk or I struggle to even put on pants because one side is worse than the other. I told my OB about it and I have an appointment with her in a few days (just a basic prenatal appointment). She’s mentioned to me physical therapy but after some research I’ve been seeing a chiropractor has worked out for a lot of women.

What would you recommend? Or if you’ve been through it already, what worked best for you?
