Ticktock- I was charting and all with DS2 and he (as well as all pregnancies) had low hcg and measured 2 weeks behind. If I had of gone in at 6weeks, no way would we have seen anything except maybe a sac and it wasn't till then that I even had the hcg showing on the blood test. Almost 2 weeks before the blood test had come back negative. Like with this bub, if my levels and scans were right, I'd be late before preggers lol impossible. Hope that helps a lil.
