Um..what

I’m not really sure where this goes so I’m going to try here. I’m 9 weeks 6 days and a couple days ago I started getting a pain under my boobs. I never thought to look to see what it looked like I thought maybe it was boob sweat and started getting dry maybe so I just didn’t think too much about it. I clean good under my boobs when I take a shower but a couple minutes ago it started to feel like burning so I lifted up my boob to see what it looked like and it looks like this now I’m freaking out. I got a washcloth and put some water and soap on it and dabbed it all on the spot and it hurt and burned so bad. Does this just go away by itself? Will baby cream help like the diaper rash cream babies use? Now I wish I wasn’t stupid and looked when it first started to hurt. Do I go to the dr? Has anyone ever had this?
