Jade, I really don't want to frighten you, but I have heard that if OPK's continues to show a strong + line, it can sometimes be an indication of an ectopic pregnancy. (A friend of mine had two ectopics and she told me this, so I am not totally sure of the details).

So, I will keep my fingers crossed that you have a real BFP, adn of course no ectopic. But maybe do a normal HPT as well, and then see your Dr for bloods?

(I hope I haven't freaked you out.)
