Opinions - please !?

My husband and I have been ttc for 6 months. We recently found out that he has a very low sperm count. We were told it would be "darn near impossible," for us to conceive naturally. So, I hate to get my hopes up...but here are my symptoms:
9 days late 
Sore breasts
Worn out 
Increased discharge 
Stuffy nose (I had this with all 3 other pregnancies - from my first marriage)
Cramping and feeling like I'll start any second but nothing 
I don't know why I haven't tested yet. I guess because I've convinced myself I'll be let down. So, should I test? Wait a bit? Does it sound like I might be?
