Frida I had a transvaginal (in the vagina) ultrasound and my baby measured 8w5d which would put me at 9w4d today but I went to the ER yesterday because I was literally soaked in blood and passed a clot the size of my fetus and by the grace of God my baby was still there. This time I received a normal transuterine (over the belly) ultrasound and my baby measured 8w2d putting me at 8w3d today which would make sense AT ALL. The dr said sometimes a difference in machines and systems can create that gap. But that's a whole 8 days! Big difference in <a href="https://play.google.com/store/apps/details?id=com.glow.android.baby">baby development</a>! Anybody else experience the same? Or know someone who did? Is it normal?
