Possible Infection (TMI PIC) should I be worried.???

Briana
Hi ladies. So I had an emergency c section on the 15th of February. About 3-4 days ago I began to get a little "rash" above my c section, and I thought it was because of my jeans were rubbing and causing irritation. So I stopped with the jeans and have been wearing my yoga pants, but it's beginning to spread to my tummy. It's itchy and burns. 
Another thing is my c section now has a liquid discharge that's a light yellow. Doesn't smell or anything. 
Do you ladies think it could be infected.? Should I be worried.?
