I needed to take norethisterone for only roughly 4/5 days when my period was due...will probably start my period in roughly same week I would have been due on...never thought of it effecting my next period I am now worried my whole cycle is messed up.
Will my next "natural" period be delayed, stay the same cycle so I'd come on again in a week and a half or in the usual 21 days after my period ...need advice from anyone who's been on these
