My doctor told me not to have sex for a week after having my colposcopy, but I had sex after 4 days. My boyfriend and I did not use a condom and today I am having painful burning and a sense of urgency when I don't necessarily need to urinate. Do you think I have an infection? Do I need to seek our antibiotics? Any over the counter rememdies I could use? Please advise ASAP. Thanks!
