Its very normal, it fact you are doing better than me @ 8 weeks, I was having nightmares about the NICU and could not sleep, I relived the entier expereince. I did not bond with the baby at that point in time. It was just a pregnancy to me and yes i had scans 2 a week since 5 weeks onwards to 11 weeks, only because I was incredibly paronoid about everything. Finally @ 19 weeks i began to settle into the pregnancy and @ 25 weeks after i passed teh gestation when i had my son i became more comforteble feeling like i may actually make it to term.
