So I'm 12 weeks 5 days and went for my second ultrasound yesterday. My baby is measuring 11.6cm and my dr said in measuring big. I looked it up when I got home and 11.6cm is typical of 16 weeks! Has this happened to anyone? I don't think I could be further along because I got my period the month before we conceived and I ovulated according to an ovulation strip? I'm just hoping my baby isn't going to be a 10 pounder or something! Any advice or stories would be appreciated! Thanks!
