Missed bc

Facts:
Missed last pill of pack before sugar pills. 
Had period for about 24-36 hours
Missed the first couple in second pack, trying to catch up now. 
Had unprotected sex. 
Been feeling pretty cramps for about 3 days now. 
We already have 2 children. Aren't opposed to more, just wanted to wait a little longer. 
The period I had was October 13-14. 
Would it be too early to test to make sure it's ok for me to keep up with the bc now?
