sweetie- It's unsusal though, with some women it might just be too early thouhg like with my first scan - nothing but a baked bean.

i think it really depends on the person plus you might be ealier thatn you though which means they might see something next week.
Do you drink enough water before the scan??
i feel your pain, with my son at 5 weeks the ultrasound sounds showed a sack in the uterus butno heartbeat. they found one at 8 weeks.

with this pregnancy i has a scan at 5 weeks and they found a heartbeat already.

will be thinking of you.
