Honey, my levels were very low. And they didnt double in 48 or even 72 hours. I also had spotting at first and then later heavy red bleeding with clots! But all was still fine with my bub.

Try to stay calm, I know its hard. The next few weeks will probably see you become a 'compulsive toilet paper checker'. But try to keep positive. The waiting game is so hard. Thinking of you mate.
