Hi, I'm new I would just like to know whether I should go by my lmp or ultrasound date. This mau get confusing! Basically, 4 weeks ago I went to the doctors as I'd found out I was pregnant a few days before. I told the doctor I had a tiny bleed on 19th march, which was nothing like my usual periods. So he estimated I was around 6 weeks, I believe I was further than this. Then on 3/6 I was told I was 23 weeks 2 days...which meant I conceived 22nd dec, and my last period was nov 29th...so going by my lmp I'd be 27 weeks tomorrow. I haven't put that much weight on and the tech couldn't measure her properly to say how far I actually am. Thanks guys!
