about 4 days ago i was putting on some vicks vaporub below my nose because i had a cold. I got a wedgie and whle i was fixing it some of the vicks got on my vagina. it had a weird feeling so i decided to wipe it off with a wet wipe. (it didnt fully come off which i regret now) 

the next day i went to the bathroom and noticed that there was a large amount of blood in my underwear. I changed my underwear and by the time i went to the bathroom next the same thing has happened. Only about 2 times i felt like i was farting but it was coming out of my vagina and blood was spurting out. This has been occuring for about 4 days and i am starting to get worried. Am i on my period? is my vagina infected? is it all unrelated? Help!!
