Does anyone have high blood pressure?

I'm starting to get really worried. I was on blood pressure medicine and at 5 weeks my doctor told me I need to change it to one that is safe. She changed me to methyldopa and i told her I couldnt find it anywhere and then finally i found it at 1 pharmacy and they had a 2 week supply. So i go back today to pick up the rest so i can have a 30 day supply and they cant order it. That drug is no longer available... So now what?!?!?! On google it looks like there are only 2 meds safe for pregnancy?! Any one else relating to this?😭😭
