Congratulations.....
Maybe it's still to early, you might have late implatiation or you may off couple days on your ovulation. Your number is about double every 2 days and it's a good sign. Your doctor will closely monitor you to point out if it's a healthy pg.
I think when beta is 1500, US could detect the sac in your uterus. It still too early to say anything.
Enjoy your pg.
thanks I am worried because so many people start of with much higher in the 100's
I called one of my older doctors and he said that because it was not a monitored cycle they really don't when I ovulated so I can be earlier the I may think!!!
I hope it sticks !
