I'm 25 yrs old, and I delivered my first baby on 13/10/2012, and I had my first period on 14/10/2013, and it didn't stop for more than 2 weeks......, I had been to my doctor and she gave me PAUSE MF tablet which didn't work, later I was asked to go for scan, there was no problem in scan....., so they suggested me to have SANDOZ norethindrone acetate regestrone 5mg tablet...., which stopped my period immediately......, but just after 5 days I'm having my period again....., why is it for....., what should I do now???
