23 DPO

I am 23 dpo no symptoms of pregnancy or period, I took a test 14 dpo and it was negative. I have tried to take other test since then, but I kid you not they were all just blank no control line or anything. The only this I can say I do have is constipation. With my last pregnancy(that I misscarried), I had incredibly sensitive boobs, nausea all the time, light cramps, frequent peeing, and bloating. I have no clue what's going on with my body. I'm terrified to go to the Dr or test again. And as bad as I want a child, I'm terrified to be pregnant again. That was one of the worst heartbreaks of my life(including loosing my dad).
