I would definitly say 'first response'. Its the most sensitive and can pick up lower levels of hcg*

I would say any brand. I used the most generic brand when I found out I was pregnant and I was only 3 wks. Preg. I just saw a real faint line. So I would say skip buying the expensive ones. The generic store brand works great!

I have used first responce and when I wasnt pregnant it told me but now my period is late and im just spotting a little not even enough to have to wear the thinest panty liner so I really need to figure out which one is the best to use right now
