Hello
Thank you for your query.
If you are having chances of
pregnancy, it is better to take another progesterone preparation like
Meprate instead of
Norethisterone, because, if pregnant, Norethisterone causes harm to the fetus unlike Meprate.
If you do not have a withdrawal bleed after
progesterone tablets, consult your gynecologist to check for a pregnancy.
If not pregnant, progesterone withdrawal rarely fails.
Take care.
