Religous husband and MIL

So whilst going through many hurdles trying to get pregnant (and still NOT pregnant), my Christian MIL takes it upon herself to want to pray on me. The last time she did this she had my husband, my FIL and myself and her in a circle while she had her hand on my stomach and my husbands while they all prayed to have god heal my womb and my husbands penis so that we can be blessed with a child 🙄

I know her intentions are well but this all makes me uncomfortable because she knows I’m not a believer and she doesn’t even ask if I’m ok with her putting her hands on me and making a whole scene about my fertility issues.

My husband says that I’m over reacting and it’s a positive thing and that I should just deal with it. I feel like she’s being pushy and over stepping.

Am I over reacting? Should I just let it go?
