I had my first U/S at the 8 weeks mark last saturday, to be told that the baby or cramping so far, and I do believe my implantation was late as I saw .. They date the fetus based on the CRL measurement of the fetal pole.
20 Apr 2016 However, I am late a week for this month. I went to my dr on 12/8/09 (see my earlier post, on that date) and as I'd suspected, was not pregnant. before I was pregnant I would always have cramps but with this one, nothing.
