Possible Pregnancy Signs?

Patient: My period is a couple days late and I noticed a vaginal odor today. It is possible I am pregnant, but not 100% sure if this is what could cause the odor. I know that I had sex around ovulation and when I ovulated I had a very bad pain for a couple of days, which has never happened. Is this a sign that I might have conceived or could it be something else?

Symptoms: Missed Period, Vaginal Odor, Pain during ovulation
