So when I found out I was pregnant and went to my first obgyn appointment, I was told I was 7 weeks. Well awhile later I experienced some bleeding and went to the E.R and with my calculations I was 10 weeks at the time. Everything turned out fine, but the ultrasound people told me I was barely 9 weeks. Then I went for another ultrasound when I was supposed to be 10 weeks and 6 days, but then that ultrasound said I was 11 weeks and 5 days. My due date just kept bouncing between January 9 or Jan 16. So then I got another ultrasound at 18 weeks and was then told I was 17 weeks. Then I went back and got another ultrasound four weeks later and I was supposed to be 21 weeks but I was at 22 weeks. The following week I went to a doctors appointment (my doctor was out of town, so I saw her P.A that day) and she came in saying "So you're 23 weeks and 6 days" which was a few days off what I thought, but not a big deal. So I started going by her calculations. Then I went to the doctors yesterday for fetal monitoring (hadn't felt the baby for awhile, but everything is fine), and I was supposed to be at 25 weeks, but nurse said "no you're not you're 24 weeks" and then I explained to her how all the ultrasounds gave me different weeks and she said "ultrasounds are not accurate" and to just go by the given due date. Then I told her I was going by the doctors calculations. She said the only accurate calculations was my due date, but my due date keeps going back and fourth... I always thought ultrasound were there for the accuracy... So what would you go by, the ultrasound, the doctor, the due date? The baby has been measuring big so I don't know how the due date is now...
