Maybe?

I am 4 days late, BFN, so many pregnancy symptoms! Cramping for almost 2 wks now, nausea, sensitive sniffer, anger and emotional(mood swings), acid reflux, up to pee multiple times a night . . I could go on! The same symptoms I had with DS at about 2+ months. If I was pregnant I would only be about 17 days so how is that possible? Obviously tests will say no. Has anyone had symtpoms so early on? I feel crazy but its that FEELING.
