It depends on your ob. Mine starts when you get your weekly check ups.

mine starts at 30 weeks for his patients..

34. Only because I was having strong contractions. Normally 36/37 thougg.

I was low risk too didn’t started checking until 37 weeks

I got checked this past week because of contractions but generally mine checks at 36

I was low risk and started getting checked at 34. But you can always refuse. I refused every other week since i didn't see the point

My midwives did not check me once. Ever. It’s sooooo unnecessary

Mine said low risk he'd start at 38-39. High risk he starts at 36 to hopefully catch any sign of labor before it happens. But some won't check you until you're in labor though.

37 weeks I didn't make it to the other weeks then had her 2 days after
