I was recently prescribed the POP as a way of managing my painful periods. Well it’s worked on the pain, but my period is now on day 10 when it’s only usually 4/5 days long, and no sign of letting up, just as heavy as day 1. Is this normal? I chose the pill instead of mirena because I took it when I was younger and didn’t have any issues with it and it stopped my periods altogether. Seems to have done the opposite this time!
