What Does Indicate Delay In Periods, Bump On Cervix And Dryness In Vagina?

Hello!I am 22 years old, 5 feet 1' and 128 pounds. I have had the same sex partner for 5 years. While we did not have sex during the fertile stage of my menstrual cycle, my period is 6 days late and I have noticed a small bump on my cervix. Also, my vaginal secretions are affected - I used to have a regular flow, now my vagina is drier. I have never used birth control pills. I had a bit of a flu in December and my period was heavier then, this might be an influence on my present condition.Thank you so much for helping me! Respectfully,Rodica
