No, you won't get your period whilst taking Deviry, this medicine is given to induce ovulation so a period will follow that.
Normally your period will arrive about 5 days after you stop taking Deviry but don't worry if it is longer than this, it can take up to 10 days.
Deviry is a drug prescribed to women having problems with periods, usually in the absence of them, and especially when pregnancy is desired.
The pills are taken for a few days and this will trigger ovulation followed by a period somewhere between day 3 and 10.
There have been some cases where the period has not followed, in this case you should consult your doctor who will probably suggest taking Deviry for a while longer.
If you are taking these pills in order to get pregnant please also be assured that there are no harmful affects on pregnancy or the baby from taking Deviry.
