Welcome to HCM,
Thanks for trusting Healthcaremagic and posting your query.
If you did unprotected sex during safe period only, then why are you expecting pregnancy
Menstrual period starts on 14th day of ovulation.
If ovulation is delayed due to hormonal
imbalance, period will also get delayed accordingly.
Delayed period is not a sign of pregnancy always.
Foul smelling discharge is generally due to infection.
You should take treatment for vaginal infection
Period may start within couple of days.
Hope you found my response to your query informative and helpful.
If you have further concerns in this regard, you can submit those with Healthcaremagic as well.
With good wishes,
