Hello. My lmp was 10/1/15-10/6/15 according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period apps</a> i ovulated around 10/15/15. I normally have a 28 day cycle. I had my first ultrasound yesterday and going by my lmp im 8w4d however the gestational age measured 9 weeks 0 days. The doctor measured however he was even like hmmm and asked when my lmp was again. Is it possible the i am further along? Or that the measurements are not right? Did anyone else have an ultrasound with results similar to mine and did it end up being on time or behind or ahead? Based on my lmp my edd is 7/7/16 and based off the GA its 7/4/16. I had a transvaginal ultrasound and it seemed like the doctor was zooming in but im not positive lol.Any comments? Thoughts.
