I had no obvious symptoms of HELLP, beyond my platelets slowly dropping from 30 weeks (which does happen anyway in a normal pregnancy). Like you mine was picked up by bloodwork (at 38weeks), with induction immediately following. My platelets plummeted in the last 5 days, ending at ~32 in the hours before delivery - as such a c-section under epidural was not possible. My son was born completely healthy and despite complications with me, I am now starting to consider a second pregancy.
I know I will be closely monitored and feel that I am armed with a lot of HELLP information (largely thanks to this forum), so I hope I am realistic about my chances.
