It's always stressful at this point after a transfer. You are doing the best you can and just keep busy these next few days. Some women do bleed in pregnancy and mild cramping can be normal. Keep the faith, really. Lots of women don't realize they are pregnant as they have this mild cramping and light bleeding about when they'd get a period. And wa la. . . . pregnant. Let us know how it goes! Do you have any other kids or is this trying for your first?
Hope it goes well for you I go for my blood test on Monday
