This is almost exactly what I'm going through with this pregnancy, except my high blood pressures started at 7-8 weeks! I had normal blood pressure prior to the pregnancy, so this hit me pretty much out of the blue. I'm up to 22 weeks now, taking labetalol. Finally got the 2nd trimester dip so that my pressures didn't go up for the first time this whole pregnancy between visits, but I lost some weight due to sticking to a low salt diet.
I've had to go on bedrest. Even though the pressures held steady, I was exhausted after a full day at work and was having weekend migraines every week.
It's not full bedrest.. I can run an errand or two and do some light housework, as long as I don't push myself and lie down any time I feel tired. I usually end up taking a nap with my toddler in the afternoon to get by. Hang in there, and do what you need to stay healthy.
