I did the first test (only had to wait 1 hour) results came back too high, so my obgyn said I needed to do it again. I was so relieved I did it the second time b/c I was stressing all day that something was wrong, luckily it came back ok, but it was for the peace of mind also.

It does sound like you have your hands full with 2 littlies already, but I would do it if you can, don't cancel it is only 2 hours which really does go quite quickly.

Good Luck!
