Yeast infection?

Me and my SO had intercourse three nights in a row...well last night was very difficult and different because I was burning during. I figured he might of ripped or tore my vagina a little because he is fairly big and it's tough to get him in but once he's in everything is smooth sailing. Well this morning I was burning and itching down there and i couldn't get it to stop so I took a shower hoping it would go away. The burning did but the itching did not. So I just kinda looked over it well the burning and itching is back because I had scratched it and I was just wondering if it was a yeast infection? And how to get rid of it. It's keeping me from sleeping and it's just really uncomfortable and burns when I pee and just really sore😕 There's no discharge or weird smell
