Frustrated!

Kristin
Ok! So it's been a couple months since I have been to my fertility doctor. I'm 225lbs, need to lose 15 more pounds before I start an <a href="https://glowing.com/glow-fertility-program">IVF</a> cycle. 
Well long story short, I'm 12 days past my expected AF date and still a BFN..What the heck is that!!! I'm so frustrated! Anyone else going through this too?
