Unless you're stropping on a pasted paddle it's highly unlikely that you've over honed the edge. A plain leather strop only aligns the edge, unless you're stropping like a madman and then it's questionable as to whether it's even possible. It's more likely that you're using too much pressure and/or need to adjust your shaving angle a little. Try that and strop a little less next time to see how it may change the shave.
