Had mine two days ago saw heartbeat at 145 and was dated at 7 weeks exactly so not as far as my doctor had thought but I knew she was off becuz my periods are so irregular u can't date by them lol but seeing the heartbeat even though I couldn't hear it was amazing it just puts your mind at so much ease :)
I had my first at 8 weeks. Saw the heartbeat <3
Could see everything nose feet crazy honestly according to my last period I should be a week further but next appointment on the 12th will tell. Today im 10w 3d
I had mine at 8 wks 6d to verify my due date and to make sure there was only one in there ( I was in clomid when I conceived ) they said ad long as everything goes OK I won't have an other us until I'm 20 wks.
The best time to get ur first scan is around 8 wks unless its for dating, I work for a radiologist so I have already had two and my Nuchal is on Wednesday. I had one at 6 and they couldn't see a heart beat just a sac but then I had another one at 10wks 4 days and the heart beat was 168 looked like a shelled peanut.
