A bee sting? Someone misinformed you terribly. Unless you have an allergy to bees.
Descriptions of a widow bite include horrendous painful cramps, sweats, and pure misery. Most healthy adults survive easily enough, but it may be deadly to small children and the weak and elderly.
There is an antivenon, but many people elect not to receive it, because once you do, you can't safely receive it ever again.
The babies won't have as much venom to inject, but you will likely notice it if you are successfully bitten.
The problem with widow bites is that, being neurotoxic, there is very little pain when they occur. The pain starts later, when the venom goes to work, affecting your nerves and forcing your muscles to cramp into knots. Some people have only a minor reaction, but a full blown response is something you would remember to the end of your days.

A beautiful little spider, but one to be thoroughly respected, like any hot.
