High Blood Pressure While TTC

Emah
I'm 24 and my husband are ttc our first child. However, I have high blood pressure. I'm not anywhere near obese (I'm 5'7" and weigh 127 lbs), I don't eat unhealthy, and I workout occasionally. I've been dealing with high blood pressure for some weird reason since I was 20 when I started getting debilitating migraines from my birth control. 
I'm currently taking 10mg of Propanolol daily.
Has anyone dealt with this issue? Was it difficult to conceive? Were you afraid during your pregnancy? Were you worried about  preeclampsia or did you get preeclampsia? 
I don't know if I'm making a mountain out of a mole hill, but my current physician doesn't seem worried about my health condition because I have to mainly under control.
