[|Human|] Sir I had sex with my girl friend on last 13th. Her menstruation started on 7. today it is the 31st day. she has her period between 26-28. we had sex thrice in the night but did not spill the sperm in (did without condom) she is 40 years now. so far no children. she had stomach upset and vomitting after 3 days of our relationship. Is there anything to fear of the delay in the period?
[|AI|]  Hallow Dear, Your sexual relationships fall on the 7th day of menstruation. Usually the egg release takes place 14 days before the next menses; so considering he 26 days cycle, it would be day 12 of the cycle. Egg lives for 24 hours while the sperms are active for 72 hours. Hence, day 8 to day 16 would be a fertile period for her. Your intercourse happened just on the borderline days. Intercourse on borderline of fertile period, delay in menses of otherwise regular menses and nausea & vomiting are all raising a suspicion of pregnancy. However, the diagnosis has to be confirmed. Wait for 5 more days and then get urine examined for pregnancy test; done earlier, false negative results may misguide you. Else, you may go for Beta Chat Doctor test which is far more sensitive and specific and gives reliable results even on the day of missed period. If pregnancy tests are negative and still she does not get menses, give her some progesterone preparation like Devilry for 5 days, and she will get menses 4-7 days after that. Hope this helps you.
