How long do you wait to call your dr? I don't think this is my month (though I greatly wish).  The only symptom I have are sore boobs.  But I've been cramping since Thursday, when AF was due, but nothing.  I've taken three different tests and all BFN.  I know some women wait to CD45 but that'll be Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>!
