He also pulled out before he came. Should I have anything worry about?

While pregnancy can be a possibility even with birth control, odds are very low given the circumstances you described.

There is always some chance, so how much risk is acceptable.
1 percent, 4 percent 10 percent ? It is possible, just not likely

So if spermicide alone is used(Gynol), and he pulls out, I should be safer than if we weren't to use any type of proctection at all?

Any form of birth control will be safer than none at all, but certainly some are more effective than others. To increase the effectiveness of a spermicide, using a condom as well would be one option.
