I'm happy to hear that your midwife spotted the signs and escalated your care. It is traumatizing though. Angie gave good advice. Your chances of getting this again are significant, but it's likely it will be less severe and at a later gestation. It's generally recommended to get tested for blood clotting or autoimmune disorders because they can be (arguably) triggers for pre-e, and there may be treatment for them. My advice is to do all the research you can about this disease and your own body, and get a doctor - or team of them - that you can feel very comfortable with.
That said, I just had a really successful pregnancy following a preeclamptic one. My son showed signs of severe growth restriction at 20 weeks, but I didn't show signs of HELLP & pre-e until 25-27 weeks. I was hospitalized at 27 weeks with climbing blood pressure and had him under GA at 27w5d. Similar to you, my liver and kidneys had shut down and I was just in bad shape. My son was in NICU for 92 days. By God's grace, he's now a healthy 3 year old with no complications.
His baby sister was born almost 2 weeks ago at full term on her scheduled C section date at 38w3d. The pregnancy was very normal (though monitored very closely), my BP remained around 110/65 throughout, and it was such a blessing to be awake during the delivery with my husband as we welcomed her screaming little precious self into the world. We were home 2 days later, and this time at home since has been so different. I'm so glad we took that leap of faith.
