Please help

TMI.. but can anyone help me with what this could be? it’s very swollen and it’s sensitive. It doesn’t burn, itch, or smell. I started using a new summers eve wash and every since for the last two days my vagina has felt heavy and swollen. So I snapped a picture. My cycle is just now starting but the yellow is scaring me! Has anyone had this problem? 

could it be an allergic reaction?

How do I post a picture ? 

Don’t use the fragrant soap again. It must’ve caused a allergic reaction to the sensitive skin area. Try cleaning with dove and Clean frequently and dab to dry. Don’t wear tight underwear and give room for air. I will suggest petroleum jelly or neosporen. Use ice pack to decrease swelling Incase needed.
