Like you my first was born at 27 wks due to severe HELLP.
We decided to try again - basically because we had no idea what the research really said on preE - all the drs opinions were very inconsistent at that time. So, we assumed no one really knew. You'll have to look it up and ask your doctor. When I got pregnant the 2nd time - our peri told us that I had a 70% chance of getting pree again, but a very low chance of getting HELLP again. But, remember there is a very low chance of getting HELLP anyway. I was already pregnant when I heard the statistics. They are high only for those of us who had HELLP before 28 wks.
Anyway, my second pregnancy was less severe. I did not get HELLP this time, but had some complications. Thanks to having a great peri (which I would highly recommend to anyone who had preE the 1st time) the severity was less and I feel he ended the pregnancy just in time! The short story is that my BP did raise at the same time, but this peri put me on BP meds which kept the BP down around 150/95 most days. I was in the hospital on bedrest for 5 wks total. They decided to deliver the baby at the 1st sign of preE because they didn't want me to end up with HELLP again. At 34 wks, my placenta was in bad shape, there was poor blood flow to the baby, the baby's heart rate decreased more often, there was hardly any amniotic fluid left, and i began to have trace protein, not to mention my BP was slowly creeping up. SO they delivered my 2nd child - who is also a healthy one.
We were very happy to have made it to 34 wks.
I wish you all the well in making this difficult decision and hope you the best!
