Methotrexate for eptopic

Sherri • With the help of Glow, now pregnant with my third and final baby! :)
My sisters doctor believes that she has an eptopic pregnancy and has prescribed her methotrexate. The side effects seem pretty brutal and I'm obviously worried. She said she still would like to try again in the next few months after her medication wears off. I was wondering if anyone here has/or knows someone who has taken this drug and what the outcome was.
