As you say, it is possible that you are experiencing an early miscarriage where you are still registering HCG levels but the pregnancy is not developing with a yolk sac and fetal pole a blighted ovum. I think it's also possible you ovulated later than you thought you did, especially since your cycles aren't totally regular, like you said.

I do keep taking pregnancy tests and from when I first found out they kept getting darker and darker. I took another one yesterday and it was darker than the control line but I also know that sometimes your body won't recognize the loss for a while and will continue to try and support the pregnancy.

My sister had a miscarriage and she said her tests were still dark positive for a while even after she had miscarried. With my last pregnancy I went to the doctor thinking I was 8w2d and when the tech did my ultrasound it showed me to be approximately 6w2d about two weeks off.

Historically, dating pregnancies and calculating due dates were left to weekly pregnancy calendars. However, ultrasound dating, in particular first trimester sonography, has greatly improved our ability to calculate the estimated due date (EDD). There will be times that dating based on LMP does not match the ultrasound date. The calculator Pregnancy Gestation by LMP and Ultrasound Biometry is used to estimate gestational age. The parameters used in the calculation include current date, last menstrual period, ultrasound date, crown rump length, biparietal diameter, head circumference. A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Dating scans also reveal other important information such as: the number of fetuses and gestation sacs. the presence of a heart beat. the size of the fetus, from which the gestational age is estimated.
