Hey guys need some advice 
Two weeks

And took a hpt (well actually a few ) 
Different brands too

I went the doctors and got
Some bloods done 
And bloods came back neg but she wanted me to do more Coz I might be really early 
Done more last week same results came back but home test said faint pos again x3 
The past 3 days of a morning I feel sick and go to be sick but I don't 
And have sore boobs 
Have a another blood test today and af is due today
