Should Medroxyprogesterone 10 Mg Be Continued Till The Course It Completed?

I went to see my doctor last week and my blood count was a 6 from heavy cycles....so he prescribed me medroxyprogesterone 10 mg 1 tablet a day...okay the first two days were really light..the third and fourth day I would get a gush every now and then....so I decided to take one before bed ( I had already taken one that morning) so I noticed it had stopped completely ...I m thinking it was because my period is normally four days ...so I didn t take a pill the next morning....that afternoon I started spotting all over again don t kno if it was because I didn t finish the medicine ....(1 tablet for 14 days) but this medicine has me all throwed off by today my cycle would have stopped and now I don t kno when or if it will ever stop....should I go back to taking 2 a day or what?..... I hate this medicine at least I did kno when my period would start and stop but now seems like I will get a period out of nowhere....what s a girl to do this is ruining my life ...crying out for help...$15.00 are you fuckin nuts ..there s no proof that u r even a doctor
