Coz I did IVF, I found out at 3 weeks and 6 days, or 13dpo. Got a reading of 73 HCF that day, which is a good, definite +ve.

The problm with early detection is of course the first few weeks until you can do the hb scan at 7 weeks goes soooooo slowly. But the upside is that you get to modify your life and take care of yourself and baby from early on!
