Hello, I am 18 year unmarried girl. Normally I have periods for 6-7 days. Now it is for 10-12 days. My periods are not irregular, but the number of days have increased. One month before I showed to a Lady doctor in Chennai. she took scan. I was given Sysron-NCR tablet and Cycloset Syrup. Yesterday I was checked again and was given Regestrone 5mg to be taken in night. My question: Is it good to take this tablet for an unmarried. Will it not affect me during pregnancy? Thank you.
