Early symptoms

Husband and I have been ttc for 10 years. We normally will get fertilization and fail to implant for some reason. In June, I went on metformin, and vitamin d as I was deficient. Per our <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>, should have ovulated July 11th. We done BD , 10th and 8th and 12th.

Starting on 17th, I started feeling nausea, extreme fatigue, sensitivity to smell started few days later. I've still got nausea, fatigue, smell sensitivity, extreme bloating. ÀF did not show up, it appeared extremely light with no cramping.

I've taken multiple tests, I think they say negative. Took blood test on Aug 2, bfn although I did not get hcg count. My stomach is tight at top, boobs are swollen along with my other symptoms.

I've attached a screen shot of my last test. Anybody see something i don't? Anyone have any luck with pregnancy but not showing positive until maybe ultrasound?

Thanks for all your assistance
