you will do fine, dont panic and stay calm, stressing over it might increase your blood pressure, just see a doc a couple of weeks before going for meds, if any medication has to be given your doc will advice to control things and as long as you do not have obesity related issues you will do fine, my BMI was high (35) when i got my meds done, I had delivered a baby a month prior to my meds and it was a C section, it all went fine and i can proudly say, now my BMI is below 30
