i didnt even have regular period cycle for long time (nearly 8years) i get medicine for that and doctor prescribe me birth control tablets. even though whenever i stop using that again my cycle get claps. but 6 month before my marriage again i consult a doctor and he also prescribe me tablet call yasmin. but after my marriage i dont have periods then doctor do scan and ask me to use norethisterone and then ask to get blood report on 2nd day of my period cycle. then he ask me to use follistim 50 mg on 2nd day of next period cycle and ask to be to gether with my husband on 9, day after first period day.but still i didnt have period so again is it ok to use nerethisterone to start period and then is it ok to use follistim to get pregnat
