Hi Katerina and welcome to the forum. For starters, I'm not pregnant so so don't technically belong here and I did see your post on the Experienced. Be sure to check back there too, depending on the day of the week (weekends can be slow), I'm pretty sure that it will fill up with responses.
It sure sounds like you have many complicated medical issues to manage in addition to the prospect of preeclampsia. I can maybe help some, I'm anticipating that Laura will chip in (probably over on the experienced board) and give you a better answer. Often, preeclampsia can "unmask" the future prospect of hypertension in later life. So, before you get pregnant your BP is fine, the stress of pregnancy makes it go up and possibly you end up with preeclampsia. Afterwards it goes away (or doesn't in some circumstances), until the next time. As you get older you are getting closer to the hypertension you may be having in your middle and later years. Do your parents or any of your extended family have BP, or cardiovascular problems? That might be a sign of what may be to come. This time around, your pressures going up maybe relate more to this kind of hypertension, rather than an early start to preeclampsia. It is very rare for preeclampsia proper to show up before 20 weeks. This might be good, on another thread, folks have been discussing how much more willing OBs are to treat this kind of hypertension with meds, possibly extending your pregnancy. You will still be a greatly increased risk of having preeclampsia and so you will need to be carefully watched. I think that at this point, your neurological symptoms are probably best left to the neurologist to diagnose.
Start with these links, I hope they help. It sounds like your sweet boys leave you with a lot on your plate. Do take a break and come and post here. We'll want to know how you are getting on.
