My first son was stillborn because I had pre-eclampsia and I was very ill with it
My second son was born 7 weeks prematurely because I developed it again, but because I was monitored very closely, they acted as soon as I showed signs of PE.
I took aspirin daily with my second son, but I don't know how effective it was.
I didn't develop PE with my last 2 sons, but fully expected to. I feel it may have been due to the fact that they were born 9 and 11 yrs after my second son. I don't know.
