For the past 5 days I have been constipated and feel pressure by the vaginal opening during all hours of the day. I thought it was a UTI but it doesn't burn while I pee. It hurts the most when I'm about to finish peeing. It is a burning/pressure/contracting feeling. I've tried vagisil, but it doesn't help any symptoms. Also I tried checking for my iud strings, but the vagina feels swollen and tight so I couldn't even put the tip of my finger inside.
