I’m expecting.

I’m so shocked right now. We werent actively trying to get pregnant but we weren’t preventing it either. We were just let it happen when God wanted us to have one. Well I found out 9/9/19 I was pregnant, (by my last period we are guessing around 4wks) went to the doctors the next day because of some light bleeding which went away they confirmed I’m pregnant. I had blood work done that day and they are having me do more to make sure my numbers keep rising. I have my 1st real appt for the baby on the 27th....This is my 1st pregnancy. I’m 33 yrs old about 350lbs. I also have high blood pressure perviously to becoming pregnant and they changed my medicine to a safer one (labetalol) which yesterday was the 1st day taking and omg it was horrible it was to high of a dose it did to much of a bp drop that I almost passed out. I had to have my MIL come over and tell her everything (which we didn’t want to tell anyone I was pregnant until 12 wks along) so that I wasn’t alone in case I needed to go to the hospital. I will say I’m fine they told me to only take a half a pill for now until my body adjusts to it or needs to have it upped. It was so damn scary!!!! I’m scared to get excited about my pregnancy because I know the risks of a miscarriage doesn’t go down until wk 12 I believe. Any advice anyone can give me with any similar experience?? Any type a in general is appreciated thank you!
