Feeling off

Brandi • 25 years old, momma to a beautiful baby girl, and expecting baby #2 💕
I'm currently 2 days late on my period. Took a test this morning came back negative. Not having any signs of it coming. However I'm extremely tired all the time now, my lower back has been hurting, I'm urinating a lot and I've been nauseous off and on. I'm gonna test again Friday hopefully I'll get the positive I've been wanting ?
