There goes another month...

Megan • Happily married. One 2015 angel baby, little girl born Sept 2016, & one due June 2019.
Just for AF this morning. Was really hoping to get a bfp on Father's Day and surprise my husband. Nope! It's really heavy and bright red. Is that healthy? Sorry TMI. 
I don't get it. My breasts were sore two days ago, I could smell everything, eggs made me nauseous, and I was extremely tired all the time. So now I'm just so upset and disappointed. 
My friend suggested I get CD3 and CD21 bloodwork. Any thoughts on this? Been ttc off and on for 2+ years.
