The average woman keeps to this schedule, wavering a few days in either direction. Based on my calculations (the first day of your LMP) I scheduled my first OB appointment for what I thought was my 8th week of pregnancy.
My husband and I planned to keep our “little secret” a secret until we had confirmation via our first ultrasound (doctors generally do not offer blood tests anymore, so the at home test is usually the only indicator until your first ultrasound).
During our appointment, we saw our little babe on the screen and it was confirmed, we were PREGNANT! After the ultrasound, we had a sit down with our doctor who we were meeting for the first time and she explained to us that while our “date” indicated 8 weeks, our baby is only measuring about 6 weeks. To put it lightly, this is not what we were expecting to hear and in such a matter-of-fact way.
From there, she proceeded to tell us that there were two likely scenarios – either I had ovulated late or we were in the beginning stages of a miscarriage. We left the office a little deflated that morning, with our plans to tell our families now put on hold until our next ultrasound, which was in 11 days.
To be perfectly honest, I’d say we handled the possibility of miscarriage fairly well, diving head first into work and trying to pass the days.
The expected date of delivery (EDD) and estimated conception date computed by this calculator are for informational purposes only and by no means shall be used as the exact dates for these events. The basic formula to calculate it is very simple and works great if your average cycle length is 28 days.I believe I conceived 4 weeks ago instead of 5 weeks ago..but my internal ultrasound is measuring 6 weeks 5 days. Im just confused as to why I did a dating ultrasound and it says 6 weeks 5 days.However, things can get complicated if your cycle length is not 28 days or if your luteal phase length is not 14 days.The above tool makes it easy to adjust for these sorts of shift by letting you specify your information. First day of LMP can be used to calculate a baby's EDD.
