Taking Daphne pills and no period since May

Hello, mommies. Sino po dito ang nag-take ng either excluton or Daphne pills and never pang dinugo after taking it? In my case Po kase, April 13 nag-take Ako for the first time. Then April 16 dinatnan ako (normal cycle ko 5-6 days nag-last). Then on the following months, di na ako dinatnan. Always negative na man po sa PT. Di rin ako tumataba, and no pimple break out din. Not bloated rin.
