I Recently Had A Baby A Month Ago And I

I recently had a baby a month ago and I have been having issues with my blood pressure being extremely high. My current ob has me on 600 mg of labetol and wants to add pro aria to the mix. I feel like that's too much medication I ended up in the er last night with a migraine I had for two days when they took my blood pressure it was 178/122 my Ob has done nothing but increase my labetol and at this point I don't know what to do?
