I missed a dose of my antibiotic, is that enough for the bacteria to develop resistance to it?

In brief: Probably not

Missing a single dose of antibiotic is unlikely to cause resistance.
However, missing more doses or taking antibiotics intermittently can lead to resistance. It comes down to drug levels in the body. Bacteria only develop resistance when there are antibiotics around but not in a high enough level to kill them. If there are suboptimal levels for awhile, the bacteria will then develop resistance.
