Maybe pregnant???

Soooo

According to my tracker on this app I should have started yesterday if not today. I have had unprotected sex with my husband. I have taken a test two days earlier and was negative and I took another today and it was negative. Both First response brand. Is it possible I'm just taking them too early? And is it possible that my hcg levels are still to low to register and I would be better off getting blood work.

First time doing this haha and we are excited but I'm trying not to get my hopes up if we aren't!

Thanks everyone!
