lmp
No. Doctors (and other medical professionals) measure pregnancy in terms of LMP. If you are 7 1/2 weeks pregnant according to your doctor, you probably became pregnant about 5 weeks ago. This assumes you have the standard 28 day cycle, and became pregnant at mid cycle. LMP is not an accurate way to date a pregnancy. If you are in doubt, an ultrasound before the 18th week LMP is the most effective way to date your pregnancy.
The earlier it is the more accurate it is whether from conception or from LMP, but if you say 12 weeks you mean from LMP.
Pregnancies are always measured from your lmp so it sounds as if your ultrasound is spot on. They don't add 14 days or anything but it will be 8 weeks 5 days since you conceived
Yes. Unless you have a 28 day cycle, your personalized due date will be less than your LMP due date.
Pregnancy can be confirmed about 4 weeks after the first day of your LMP (last period) or about the time your next period is due to begin.
Last Menstrual Period
1/ The corpus luteum is formed when the follicle releases the ovum at ovulation, when there is always some bleeding. If the bleeding is excessive, a corpus luteum cyst develops. 2/ If pregnancy results, the corpus luteum persists to produce pregnancy to assist the pregnancy Anna
No, they can be tender when you're starting your period or when there is illness as well. Breast tenderness can be a sign of pregnancy, but it doesn't always mean that you are pregnant when it occurs either.
Women have cycles that are not all the same length but most women ovulate 14 days before a period is due. That is what makes the difference. At 7 weeks ultrasounds are accurate to within 3 days. At 20 weeks they are accurate within 5 days When I had my first pregnancy my cycle was 36 days which would mean my EDD would be 8 days early if my LMP was used, my US agreed with my cycle not my LMP. When I had my second pregnancy my cycle was 28 days and my ultrasound agreed with my LMP. So you are saying that the ultrasound is more accurate? Yes, the ultrasound is more accurate. I did go round the houses a bit to say it.
They consider your LMP (Last Monthly Period) to be the starting day of your last period, they track the 40 weeks of pregnancy from that, but no, it's not the actually day where you ovulated and got pregnant. You usually ovulate about 2 weeks AFTER your LMP so technically when you are "4 weeks pregnant" the baby is only 2 weeks.
