I am two days late and have been having nausea, frequent urination and vaginal wetness. could i possibly be pregnant? i haven't tested yet.

Maybe. Maybe not.: In a woman with regular periods, some causes of a late period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (like hormone pills or birth control pills), hormonal imbalances, etc… Seeing a doctor is a good idea if symptoms are recurring or worrisome. Pregnancy is the common cause of a missed period if sexually active.
