Is it possible to get pregnant and delayed period if you stop taking the pill and had contact during your period?

Your period is actually one of the safest times to have contact if you're not on the pill, as well as the week after. Generally your period works on a four week schedule (though it differs per woman) and you ovulate (release an egg) on week 2. Week four is usually your period. This is when the lining that has built up in your uterus to act as a cushion if your egg is fertilized, begins to release. If the lining is "releasing" the egg has nowhere to find cushion even if it does get fertilized.

Also, generally after you stop taking the pill, it is natural that your schedule will be messed up, and your period can come late. The pill regulates your hormones into a four week cycle, whereas with your body's natural hormone production, your cycle might be longer.

However, it is never a bad bet to see your doctor for a test if you are really worried. They are experts at this, remember!
