Possible infection after cesarean.

I'm almost 10 weeks pp and was cleared by my ob to return to work 6 weeks after my c-section. She said I was healing wonderfully and everything was golden. I did have a tiny part of my incision that was still open at the time of the 6 week check up but she wasn't concerned. Last night I noticed that that small opening was still there and that it was leaking a little bit. The discharge is a little yellow I guess but doesn't have a smell. I'm in no pain and there's no warmth around the area and I feel fine. My husband wants me to get checked out at the hospital but I want someone else's opinion on if it's worth the trip and the cost. My ob's office is closed on Fridays and they'll be closed Monday for the holiday so I can't call them and ask. So, what do you guys think I should do?
