Yes, I had this. I developed pre eclampsia the day they were inducing me, I then had an emergency c section. I developed eclampsia very shortly afterwards. It's very rare I understand from the consultant, that delivering the baby doesn't alleviate it.
I started hemorraghing, in the middle of the night, went to loo, and called the alarm, and was taken back to bed by nurses, they took my blood pressure and called an alarm. Everyone was running.
All I remembered was the running and that I kept falling asleep, and a lot of medical proffessionals in my room. I really genuinely thought I was falling asleep. They took my daughter out the room and I was taken into intensive care. At one point they sedated me, and I couldn't understand why they woke me up to tell me they were sedating me. Turns out they weren't.
It wasn't until the consultant came round the next morning that he told me I had eclampsia and had been fitting. Which scared me. The fact I didn't know.
I spent a month in hopspital and had other issues. I also had follow up visits for a year afterwards.The doctors wished to sterilise me, as I was unlikely to survive another pregnancy. I declined.
I however never really wanted another one, but the thought of it scared me after.
The doctors should tell you if you can have another pregnancy. Mine were very very clear indeed that I should not.
