Miscarriage may 14,2018

Bleed for 5 days ( Monday -Friday)

The weekend that follow all to the following weekend we tried !

I been testing and either getting complete negative or perfect positive and a lot of faint positive also.

Am i testing too early?

My period should be here in two days, but right now i have the peeing urge (plenty) sore and tender breast( a lot) and nausea all day long! My appetite have definitely change and my saliva has also change. I feel a lot of extra in my mouth and an urge to keep spitting. Would it be too early for a blood work ? Or sonogram ?

Thank you !!
