preeclampsia risk?

Kristin • 27 married army 2 girls ( 3 & 8 ) expecting our 3rd and final princess. recent miscarriage (04/24) we found out our rainbow is due 02/13/18 :)

so I had preeclampsia in 2008 with my first but not with my second in 2014 but the OB wants me to take a low dose of asprin starting at 13 weeks to reduce my risk of high blood pressure. anyone ever done this I didn't do it with my second child. I'm 27 and healthy don't smoke drink or hardly even drink caffeine ( NOT BY CHOICE BABY MAKES ME UPCHUCK ).
