Pregnancy due date question
I am not pregnant, my son is 19 months old. I keep thinking back to when i got pregnant and my due date. My periods were always very predictable and I wrote them down each month. I knew exactly when I was ovulating and can almost bet that exact time I got pregnant with my son.
DH and I had sex on a Friday in Feb. - right when I figured I was ovulating - two weeks after my period. Two weeks later - I was pregnant!
I did the pregnancy calculator tests on line and all of them said my due date would be 11/7. However, when I went to the OBGYN, they told me my due date was 11/27. I always wondered why this was sooooo much later. I knew my cycle and when I conceived, why was their date different from the on-line dates?
Well lo and behold, I had my son on 11/7/06 and he was 7 lbs. 4 oz. Now, either I had a large baby 3 weeks early, or I did go on my due date and the OBGYN was wrong. I sometimes wonder if the nurse wrote down my last period date wrong.
Anyone have something similar happen to them? Are the on-line calculators different from what OBGYN's use?
