<s>[INST] Hi sir. I am havig sex with my girl friend  once in every month. I am giving unwanted 72 every time with in 72 hrs of time. By that she is geting perious every time 1 week before the regular. Is any problem of using like this and is any problems will cause in the future. Means that any permanent pregnency lost chances. Plase kindly answer for this qn. [/INST] Hello,Unwanted 72 pill itself does not cause problem in future pregnancy or conceiving issue.But frequent use of that kind pill causes irregular period with impairment of normal ovulation. So it may cause delaying in pregnancy or conceiving problem. For natural conception, period must be regular.Here she can take combined OCP monthly basis instead of frequent emergency pill. Combined OCP gives highest protection (99.9%) against pregnancy with regularization of period.Next, when you will try for baby, all kind of contraceptive methods are to be stopped for at least 1-2 months to regain fertility.Hope it helps for you. Good luck. </s>
