16 DPO (calculating 5th week from my last period)

I have had faint positives like this for the last 5 days.

Couple days ago, I started getting pink spotting.

Next day it was followed by brown and pink/coralish color bleed . Not way too heavy to change a pad in 2 hrs but it was medium bleed. No cramps at all. Just had a tiny bit of hip and lower back ache. Not concerning pain.

This was taken today morning as the bleed stopped yesterday night.

I still see a vfaint line in the clearblue.

I have been having excess salivation, like I have the need to spit very often. Peeing every hour has been the case for the last 3 days. I'm confused.

Anybody in my same boat and ended up pregnant?
