Welcome to HBT.
If you are looking to get the most out of those hops, you may have done better to wait till after fermentation is complete. Compounds that lend hops their aroma and bitterness can be stripped away by the co2 that is created during fermentation and sent out the airlock (if you are using one) or will escape to the atmosphere. your beer will smell nice while it is fermenting, but that nice aroma will have been lost to the air and will not be in your beer where it belongs for you to enjoy.
If you are not concerned about that, then I would say no harm/no foul.
That being said, the hops you added, were they part of the kit?
...or did you decide to add some extra hops. If that is the case (you decided to add extra), you may have saved yourself from a bigger FUBAR as the recipe might not come to balance well with added hops.
Hope the experts can chime in on this....
