A 4 week pregnancy scan and nothing?

At 4 weeks your baby is still no larger than the head of a pin. Most doctor's office ultrasounds do not have the detail to see ANYTHING that early. Fertility clinics frequently have a stronger unit.

With the baby I lost we had a scan at 5 weeks 5 days and saw nothing but a blobby, two weeks later we saw the fetal pole with the heartbeat - but it was still just a blobby with a speck in it. At this stage of development the embryo still doesn't look like a baby - more like a lumpy worm. A very tiny one. At 10 weeks he looked more like a baby though it was a very short scan (side note: don't ever get your ultrasound buddies to scan you until you've had the "official" scan - they might find something bad - mine did as I mention below and I've felt terrible ever since that she was the one who found it).

At 14 weeks 5 days, when we discovered his anomaly (he didn't develop a skull - I had snuck into ultrasound again to get them to peek at the baby) he looked exactly like a baby - arms, legs, face, belly, heart, etc, and we were thinking he was a boy. Sadly I never got to hold him.

Good luck with your pregnancy, and do NOT worry about not seeing anything at 4 weeks. Doctors never pay attention to us when we tell them when we ovulated, even when we chart temperatures and other body signs as well. The NP at my OBGYN office didn't believe my charts and wanted to think I was 18 weeks pregnant, when I was, in fact, just over 5 weeks pregnant. After she examined me she sure believed me.

I took an ultrasound to confirm my pregnancy at 7weeks and saw a little peanut

I had an ultrasound on Wednesday and it showed me at 6w6d. ( 7 weeks on thursday). But yea, it measured at that. They were even able to hear the heartbeat! measured at 154bpm

YEAH WELL I WENT WHEN I WAS 4 WEEKS AND YEAH THEY COULDN'T SEE NOTHING NEITHER. I SAW MY BABY AT 12 WEEKS THOUGH

Its too early.
