baby cannot be seen

that's normal. i had an ultrasound on 8th week of my 2nd pregnancy but nothing is seen clearly, no heartbeat, very small not so clear baby. the doctor repeated scan a month later and there's the baby, so clear with his heartbeat. for now, don't worry so much, take very much rest, stop doing heavy work or heavy lifting, do less house chores, that is what my doctor and nurses adviced me at that time. and congrats mommy
