Be aware that condoms are not 100% effective. It is unlikely that she would become pregnant, but not impossible. I always recommend using contraceptive foam or jelly along with condoms for extra protection.
The fingering episode cannot result in pregnancy.
Any couple that has intercourse, protected or otherwise, risks pregnancy. Be aware of the slight possibility, and mentally be aware of what your reaction might be.
If this is a serious question. NO but you should really wash up after intercourse either way...........
