I had sex for the second time in December. During that sexual experience I began to bleed heavily to the point where I felt faint and began to sweat. I pushed out a huge blood clot and then began to bleed lightly. Went to a planned parenthood and they tested me for STDS thinkin that may be the cause but it was not. Since that time I have been experiencing breast pain, lower back pain, vaginal pain on the left side, and my menstrual cycle have changed from being 5 days heavy flow to 3 days with light-moderate flow. I went back to planned parenthood and they told me I need a coloposcopy. However I would like to know what are the complications of having a vaginal injury untreated? Also do lesions in the vagina heal by themselves and could my symptoms be a product of the healing process?
