Hi, thanks for asking in Healthcare Magic.
Your menstrual cycles were regular 28 days cycle as you were on hormonal
pills. In PCOD, the cycles are irregular due to hormonal imbalance. The 28 day pills would have regularized the menstrual cycle by correcting the hormonal imbalance.
Since you had protected sex during safe period, the chances of pregnancy
are minimal. The delay in period may be due to PCOD and may not be due to conception. However to be sure, you can rule out pregnancy through urine and blood tests.
is Dihydrogesterone, a progesterone
which results in withdrawal bleeding in 5 to 7 days. If your period is delayed even after taking Duphaston, it means that your estrogen
levels are less than normal, as Duphaston is effective only on an estrogen primed uterus.
I hope this is helpful to you.
