How Do I help my friend...?

I dont know where to post this question..!!! I am going to post it different places. I have a friend her husband is a truck driver that works out of state but comes home every Friday and is Home until Tuesday mornings and he leaves again. Well they a children and they have a newest addition and he is 5 months old. Well to make long story short they used condoms for a while but have stopped using them about 2 wks ago and my friend was cleaning out her husband work bags to wash his clothes and she found condoms in there. So she doesnt know what to think..!!! I dont know what to tell her or how to help her.She doesnt understand why they would be in his bag.. It isnt a whole box either. They have been married almost 8 yrs. How do I help her.? Any advice would be great thanx..

One more thing. She said the brand in his bag isnt the brand they have been using before. How does she bring it up to ask her husband about them?
