Clavamox and increased urination?

My 6 month old female Beagle x Basset Hound has been on Clavamox for about a week for an infected incision from her spay. Today, we've noticed that she is peeing a lot more often than usual. She's peed four times within 2 hours (all in the house except one outside). Is this a usual side effect? The Internet isn't much use. She still has a weeks worth of dosage left. Thank you!
