I am thinking day 10, would I be correct? and should me try say day 10/11&12? Also if a few months were to pass and nothing happens when should I see a doctor maybe 3 months if still not pregnant? thanks [/INST] Hello, Pregnancy is possible only, if unprotected sexual intercourse is done with ejaculation around ovulation time in regular period. You should have to try at least one year and after that if you are unable to conceive, then you need to consult with your gynecologist for several investigation and clinical examination. Ovulation occurs approx 14 days before due date. In your case, it is around on 11th day of cycle and fertile days will be from 9th to 13th day. In this time period, you need to do unprotected sex daily. You can use ovulation prediction kit (OPK) to predict ovulation and prepare for that day. Avoid stress, take healthy diet with Vitae & Folic acid supplements, control body wt and proper sleep. Be well. </s>
