AF due 4/10

Em
Looking for cycle buddies, AF is due 4/10.. Trying for #1 and its our 1st month trying. Currently I'm Charting and using Preseed. Looking to start OPK's after this month if I don't conceive. 
I want to take a test, but I figured it's too early. No real big symptoms other than I did burst out crying last night after holding a friend's baby for an evening and I've had random odd pulling sensations at the top of my belly button.
