Jess, you just make me giggle.
Your DH does know that "pulling out" is not an effective method of birth control right? Pre-ejaculatory fluid can have semen in it.
That said, we are basically just following my CM patterns to avoid. If I have fertile cm there is no

!! Of course that isn't fool proof either since the little buggers can live for up to 5 days in the right conditions. Of course with our infertility issues I figure it's pretty unlikely anyway (Lord help me if I am posting on here next week about being pregnant!

)
I'm glad your DH was positive about it! So when ARE you going to test?
