Am I over reacting?

As
I am 5 weeks post partum and my husband has been wanting sex and sexual favors but I had a tear and don't want to risk infection or tearing again. Anyways I have been feeling down on my body appearance after the baby. And last night I found an accidental screen shot on his phone of porn. I'm honestly devastated and disgusted. Am I overthinking this. Should I be feeling this way?
