What Causes Redness In The Cervix?

I was at my GP today and she said my cervix are red. I also have a tightness on the right hand side, low down in my abdomen, where my ovaries are. I had slight bleeding after sex the other night. I have been on the pill for 10 years. Could i have a cyst on my ovaries and would this cause my cervix to be red. I am quite worried. I now have to wait for an ultrasound and results of swab.
