DEFINITELY go get the test Kim!
And let us know how you go...

I was convinced AF was going to arrive any second - I didn't even consider I was pg I felt so like I do before AF arrives (cramping etc). In fact, the cramping went on for longer than when AF arrives normally, which sounds like you, and the sore nipples sound like a good sign.

Fingers crossed for a BFP for you!
