<s>[INST] HI Doc...

[/INST] Hello, Unprotected sex just after period over is very much safe and there is no chance of pregnancy at all. To maximize chance of pregnancy, you have to unprotected sex on ovulation day (14 day prior to next due date) or fertile days (12th-18th day of each 28-30 days cycle). You can use ovulation prediction kit in the mid-cycle. Take balanced diet with Vitamin-E & folic acid supplements for 3 months, avoid mental stress and take sound sleep. Good luck. </s>
