Hello ladies, this is another post about lmp and Ultrasound date difference. Im supposed to be 20 weeks tomorrow according to my LMP. 17 JAN 2011. I went for a scan today and instead of measuring 19 + 6, bubs was measuring 19 + 1 and the measurements were as follows: BPD: 41.9mm (18wk 5 days) H.circ: 163.7mm (19wk 1day) Ab. Circ: 134mm (18wk 6 days) FL: 30.9MM (19wk 4 days) Tibia: 26.8mm (19wk 5 days) Then they have stated my LMP due date as 24.oct 2011 and US EDD : 29th oct 2011 Now i know that sometimes due dates can be back and forth by 1 week or so, but im concerned about bubs measuring 19 + 1 as they have summarized it in one sentence : single viable fetus of gestational age 19 weeks and 1 day. im supposed to be half way done tomorrow.. any advice or ideas ladies? i know that sometimes measurements can go wrong and theyre not always accurate, plus the baby was in a cephalic position ( head down ) position. i googled the cephalic position which is basically delivery position and there was a post on Bnb a while ago saying its normal cuz there is a lot of space for bubs to go somersaulting around now.. but any advice on the dates would be very much appreciated.. thanks a bunch !
