What could be going on?? Faint lines and now nothing but period late ?

Hailey

So I took these tests 8 days ago and I was so sure I was pregnant. Now when I took a couple dollar store tests there was nothing... I’m either 9 days or 3 days (not sure when I ovulated) late?? No sign of my period .. just slightly sore boobs/nipples but even that isn’t as strong anymore. What in the world is happening 😩 I want to go in for blood work but when I asked they said they usually don’t do blood work yet... so I feel like I need to see someone else.

I am so sad ... this makes me feel crazy and like it was all in my head.
