Provera and pregnancy?

Emily • Mrs 3/21/15 Mama 3/31/16 Due with #2 May 2019
I was on Provera to start my period... I had taken a test at the doctor before I had gotten on it and it said negative. Well when I didn't start my period 5 days after being off of it I took a pregnancy test and low and behold I am pregnant!! I am 6 weeks and was about 3 when I first got Provera. Has anyone ever been on Provera while pregnant accidnentally and your babies be okay? Google has scared me!! 😥
