I conceived by ivf recently. My last menstrual date is 14th August. I had an FET with natural cycle on 28th August. I had positive pregnancy test on 11th September. Now my question is the doctors are telling me I am 6w7d pregnant today whereas as per LMP it is 6w2d. They are expecting the growth to be accordingly too. They couldn't find a heartbeat (they did find a fetal pole) on 24th which according to their calculation was 6w4d but according to LMP is only 5w7d. Although they are continually monitoring me but they are saying mostly things aren't going well for me. Shouldn't they be adjusted the gestational age according to the ultrasound and not just give up and scare me?? My HCG is rising even now however it has slowed down a bit after reaching >11000.
