What are the chances of me being pregnant from fingering, possible precum on his hand (were not really sure), took plan B 40 hours after to be safe. It all happened on the 5th day of my cycle, had spotting the week after for 3 days but I should have gotten my period three days ago.

The chances are very slim. Not nonexistent, but very slim.

The Plan B will throw off your period, so being three days late isn't really a concern at this point. If you miss your next period you should take a pregnancy test.

There is a small chance, but very small. The pill you took can and does have a lot of side effects, it can cause extra bleeding or it can cause you to miss a period for one or even two months.

After you are 2 week late, try a pregnancy test, using first urine of the morning. Continue this every week, till you have a period. If you miss a second period. Go see your doctor for a blood test.
** or a blood test anytime if you want.
