Tully I have genetic high BP and have has since I was 18 yrs old (and I am a big girl).
I have had to have medication for my blood pressure through all my pregnancies and even ended up with pre-eclampcia with my first but most of the time the medication they put u on/ change u too will be able to keep ur BP in a good range through ur pregnancy. Dont let u think it will hold u back just keep trying.
If I can get though being pregnant then anyone can
