According to my last cycle I was supposed to be 6 wks and 6 days today. I went and got an ultrasound Tuesday and was told even at 6 wks they may not see anything ..so true enough after U/S and transvaginal they didn’t see anything but sent measurements to my obgyn who contacted me and told me I’m measuring at 4 wks and 2days as of this past Wednesday..she sent me for lab work to make sure my HCG level was still rising my HCG first got checked on Feb 17 it was 260...Feb. 19 my HCG level was 1,244 Feb. 28 my HCG was 15,498 and wants to schedule me for another ultrasound the end of next week...has this ever happened to you!? Should I be worried?
