2 weeks late, but no bfp yet... what's going on?!

So over the past 2 or 3 weeks I've been kinda tired/sickish/nauseous/generally-shitty-feeling in the morning... I've also been getting these sharp, random pains in my left lower abdomen. Throughout the day, I swing between feeling like I'm starving and finding even the thought of food repulsive.

my af is exactly 2 weeks late to the day, but the prego tests I took, I took 2, were both bfns! I was hoping those symptoms were all baby - related, but they dont seem to be... thoughts?
