<s>[INST] Dear Doctor, My name is gopinath. I have one doubt. Please clarify my. Me and my wife is had sex 13 March 2017. That february month periods is happend regular date(every month 29,30th). But this Last month(March) periods is not happen in that regular date. Also Still date not happen periods. We dont t do the sex after March 13. I m not sure She is preganant or not. Kindly clarify me any chance have she is getting preganant. Thanking You. [/INST] First history of yours is little confusing. Because February does not have date "30". But yes what I understand the misses a period, and you had sex once during past cycle. Now there are many reasons for missing a period and pregnancy is one of it and most common one. So do urine pregnancy test and see if it turns out to be positiver than she is pregnant and if it is negative than it is delayed menses.in case of positive result you have to do sonography for confirmation. This is the best way to see whether see is pregnant of its delayed menses. For delayed menses also she may have to take medications sometimes. So consult nearby gynecologist, and he may prescribe oral tablets like progesterone for menses to come. Chat Doctor.  </s>
