Late ovulation and pregnancy dating

When people discuss how far along in pregnancy someone is, they tend to do so in general terms: “She’s in the first trimester” or “She’s four months along.” However, many people have only a vague idea of what those phrases really mean.

Medical professionals use a standard set of up to three methods to date pregnancies: last menstrual period, ultrasound, and a physical exam.

The average time between menstrual periods is about 28 days, and ovulation occurs about 14 days before the next period begins.

Late ovulation and pregnancy dating

Sometimes we do use a trimester system if we are seeking to describe how far along a woman is in general terms.

Trimesters, however, have a variability of a few weeks, so they should be thought of as general benchmarks.

Hi gals, This post is for all of us late ovulaters and what this means for us and our developing babies.

You must know that I am a constant worrier, I suffer from severe anxiety and of course now being pregnant it only makes my condition worse.

If the ultrasound estimate differs by more than one week from the LMP, we would use the ultrasound estimate for the due date.

This method continues in the subsequent trimesters.That way, regardless of where they trained or where they practice, any two doctors dating a pregnancy will predict the same due date or gestational age.However, the timing of the actual delivery is not so predictable.My LMP started Jan 31 and I ovulated on February 18th.11 days past my ovulation on February 28th I got my first BFP, it wouldn't seem like that's enough time for the baby to implant and start producing enough HCG for an HPT to detect, but I guess I'm producing HCG somehow because since last Monday (Feb.All I know is that I am afraid after what happened in October and it's very hard to shake the fear.
