you would have been @ 13-14dpo when you had your first beta right? That could be normal, but if you get intermitant -'s & +'s I would be very concerned too. HOWEVER, everything could be just fine too... you were 9dpo when you got your 1st + and that is VERY early to be getting a +. I hate to say it honey, but you're going to have to hang in there wait for the results and hopefully they'll draw another beta to see that # too.
Good luck! Everything might just be FINE

I'm sorry for the anxieties and fears right now. Hang in there and KUP
