How is it going? Have you considered a pre-conception appointment with a MFM specializing in high risk pregnancies? https://www.smfm.org/default.cfm
I asked to be tested for underlying disorders after having pre-e with my first. Nothing turned up, but I still was happy to have that information going forward. I also started monitoring my blood pressure at home with my second pregnancy. Once my BP started acting up I was put on a more frequent appointment/ monitoring schedule. I still wound up with pre-e but didn't get as sick.
My sister-in-law had no pre-e with her first pregnancy, but did have pre-e with her second pregnancy- with a different partner who also had a family history of preeclampsia.
