Sending you lots of positive vibes... We are going through a BFP rollercoaster ourselves and at exactly the same stage, it is so so tough... Big hugs...
I can only echo what everybody says - bit of bleeding throughout pregnancy is very normal for lots of women!
If you are really worried you could get an early scan - they should be able to see the sac and the yolk and maybe the fetal pole and maybe the heartbeat, but latter two also can show up later - so it might not help at all... You could also get HCG bloodtest, but you would need a couple and to be honest the scan will be more reliable, but has the uncertainly as described above at the moment... You are probably better of waiting a week if you can bare it, but if the stress is too much then would advise to just go for it!
I wish you strenght and patience and faith - unfortunately it will have to play out and you cannot do a lot about it, bar supporting each other, eating some nice stuff and watching crappy TV to try to relax as much as possible?! X
