pills after miscarriage

Amy
I was diagnosed with a miscarriage in the er after not hearing a heartbeat. I went to my ob today and she said my body had passed a majority of the miscarriage on its own just a lot of blood and tissue left and my body may do it on its own or may not (the bleeding had lessened a lot today) so I opted for the pills. I have to take 3 for the next three days she said they would cause contractions to rid my body of what was left and the contractions have started to worsen just wondering if anyone else has had experience with them and what those experiences were.
