Need help with baby girl

My baby is 20 months old today. Yesterday night she started running around and fussing so I prepared her to take her a bath and when I removed her diaper she closed her legs and curled so I gently opened her legs so see what was going on and her vagina just looked werid to me. It looked like open/stretched out and red with little little blister look alike. I showed my husband but he just saw the red he said he honestly doesn’t know what a baby’s vagina looks like. Well neither do I but for some reason it looked werid so I started looking up stuff and it was saying baby’s vagina changes as they grow. Then I showed his parents (they live with us) well they change her so I asked them and they called me crazy that it looks the same. Called her doctors but they open til tomorrow. This morning the redness took off and the blisters but it still looks stretched out and open. Anyone else had this? Anyone noticed this changed with their girls?
