I was prescribed provera 10mg tablets to take for 10 days because i have missed my period the last two times... i have seen a lot of people commenting on weight gain and acne from using provera - but i wonder, does this happen when just taking it for 10 days? anyone who has had to do this, what were your side effects? i just started today and i go back to school in a couple of days... i'm hoping i'm not going to be gaining weight like crazy. any info would be great!!
