Dear Sir / Madam , My to be wife of age 28 usually has her period on 13th of every month with delay of max 1day . Today it's 15th but she isn't having her periods. On 2nd Sept we had a intimate moment where no penetration sex was done. But she has a doubt that a little sperm has fallen outside her vaginal area but she is virgin and never had any penetration not even finger. We are tensed now 🙏 Please guide
