<s>[INST] I took Primolut-N ( norethisterone ) for 12 days for stopping my periods (since I was busy during that time- those 12 days). Then I stopped the Primolout-N medecine and i got my periods after 4 days. I want to become pregnant and hence i took Clomiphene on the 5th day of my period for 5 days. Now it is the 33rd day, and I have noot got my period, Is it because - Primolut has caused irregularity in my periods? [/INST] Hi, Thanks for the query. As you interfered in normal menstrual pattern by taking progesterone pills, there is possibility of alteration of next cycles. It would have better if you took camphene in the next cycle after establishment of regular cycles.Anyhow, you once check for by blood test, if it comes positive it is good. If not you wait for one more week by that time possibly you will get periods, if not once consult gynecologist for evaluation. If you get periods after one week then take camphene with your doctors' advice. Take care. </s>
