Glad you are ok. Wow identical twins Laura! Don't know why they aren't together, maybe they aren't identical after all? Me and FBTTN had 2 embryos transferred for IVF so I had a feeling both had taken.
I found out this weekend that after 6-8 weeks ish, the HCG is too high to show up on a pregnancy test as the antibodies on the strip are only designed for a certain concentration so the line will be lighter. Its called the Hook effect. Just to reassure anyone who gets worried! You can rectify it by diluting your wee with half water, very strange!
