Post op fluid from stitches

I'm 11 days post op and I noticed that there is a clear reddish fluid coming out from my belly button stitch. I have no fever or anything, and I have messaged my doctor what to do about it but no response. I'll be observing it today and see if there is a need to go the ER. But wanted to ask if this is normal and nothing to be worried about? I am stressed out, thinking it might be an infection but I don't feel anything at all. Your response is appreciated 🥹
