Baby aspirin to avoid Preeclampsia

Pri • Fraternal Twin Boys 👶🏻👶🏻 due Feb 2018!!

Hi ladies, I am 20 weeks pregnant with Di/Di twins. On my last visit, the doctor recommended that I start baby aspirin (80-81mg) a day to avoid preeclampsia. Has anyone else heard of this practice? She said that it’s something new that they are trying out. What do you think?
