I’m 5w5d, and I already have pre-existing hypertension. So worried. Any reassurances?

FTM, and I’ve struggled with hypertension for about 4 years now. I’ve been on Bp meds for years and they just switched me to Lapetalol from Metoprolol for the pregnancy. I already monitor my BP with a cuff at home and it’s been great readings so far, I’m just super worried about after 20 weeks when BP can start to raise (according to the internet). Anyone out there have hypertension before? How did you deal with it in your pregnancy? I’m about 185lbs but I’m starting to eat better and try and walk 30-60 minutes a day after my BFP, not drinking will also help a lot too. I’m so worried about preeclampsia, even this early. Am I over analyzing? Just maybe need some reassurance.
