I have found a small blood bubble with 2 smaller dot like bubbles beside it on the opening of the vagina. When i felt around it part busted and released blood. I have never experienced this before, however it is not sore itchy or painful. They were not there last night and after i had sexual intercourse, which was a bit rougher than normal they were there today. Do you think i would need to worry or could it just be from the sex.
