SOOOOOOOO glad to hear glenglen sweetie!!! They are nice levels. I think from recollection mine were around the 220 mark for 4 weeks so I dont think they are so high they are indicating you are further along as it only takes 48-72 hours for them to double as yours did sooooo nicely!! Looks like they have doubled every 36 hours or aroundabouts am I right??? Dr's go off like a chart of numbers for estimated gestation and 3 weeks is 0-50 4 weeks 50-500 I am pretty sure so that said it looks GREAT!!!! Just knew it had to be good news for you!!
