Your fruits should be swelling after 5-7 days. Sometimes it takes longer if the pollination was particularly inefficient.
Fortunately, crosses that did not take usually abort after a couple of weeks. If you see a yellowing of the stem at the
abscission zone, your cross is likely on the way out.

As far as how many F1's you need to grow, I would say at least two, even if space is limited. That way if the plants are identical, but different from either parent, you can be pretty sure the cross worked. However, if you used a hybrid as one or both of the parents your F1's will be more like typical F2's and genetically varied.
