Was supposed to be 8w 3d today, went in for a transvaginal US. Only measured 6w 3d; no hb although the tech wasnt that great, imo. I go back in 10 days for a repeat US. I also don’t have the typical 28 days cycles, I have 31. However, i’ve had 3 successful pregnancies and none of the US looked like this at this stage. They looked like straight tadpoles, lol.. this one looks different to me. Thoughts?
