It all depends on the strength of the colony. If it was big to start with, and you lost a swarm, then it has depleted many of the flying bees - but a large colony will replenish these quickly and issue casts with each virgin.
If you had uncapped queen cells last Friday, then it wasn't one of those queens that swarmed - they wouldn't have emerged yet.
So the question is how many queen cells you should leave. One argument (that I agree with) is that you should leave one or maybe two good ones. One is ideal from the point of view of cast prevention. Two is a good insurance policy in case one is duff, but you risk a cast. The other argument is that you should leave lots of queen cells and let the bees sort it out - but every time I have done that, I have got casts. I think it would be fine in a nuc, where the volume of bees is small, but in a full size colony, there will be enough bees to cast.
The ideal is to split the colony, with a queen cell in each box. That way, if something goes wrong with one of them, you have the other.
