Popping my back while pregnant.

Cassandra ☠️ • Vincent coming in 2K18 💀

I'm 19 weeks pregnant and my back has been killing me. I usually have my mother pop my back for me where she and I stand back-to-back and she leans forward, which makes me go backwards and it pops my back really nicely.

Is this a safe procedure to perform while pregnant?

T.I.A for any advice.
