High blood pressure and ttc

I have had high blood pressure since I was 16, went up to 190/120, had all tests done and put down to dodgy genes, at 19 got put on tablets called ramipril, I'm worried that these could affect me ttc, spoke to the doc n they said it's fine until I am actually pregnant, but still a bit scared about it possibly ruining my chances! 
​Can anyone relate or give advice or share your story!
