Whether you are trying to conceive on your own or undergoing fertility treatment the two week wait can seem like an eternity. This is the time between suspected ovulation — or in the case of those undergoing fertility treatment, the time of insemination or transfer — and when the first pregnancy test can be taken resulting in reliable results. To help navigate the curiosity and unknowns, we gathered some question from our community, ran them by our nurse educators, and came up with answers to your most pressing two week wait questions.

This period of time is referred to as the two week wait. The blood test — officially called a beta hCG blood test — detects hCG and is the most accurate indication of pregnancy. Traces of the administered hCG may still be in your bloodstream and detectable by a test even if implantation has not occurred. A false negative might occur as a low level of hCG may be undetectable in a urine test despite a pregnancy starting as these are less sensitive than the blood hormone tests we administer.

multiple conception following frozen embryo transfer has been poorly documented compared with lack of useful up-to-date data associated with frozen embryo.

A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures. Dating scans are usually recommended if there is doubt about the validity of the last menstrual period. By 6 to 7 weeks gestation the fetus is clearly seen on trans-vaginal ultrasound and the heart beat can be seen at this early stage 90 to beats per minute under 6 to 7 weeks, then to beats per minute as the baby matures.

Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 – 5 days of accuracy. The most accurate time is between 8 and 11 weeks gestation. This is because the fetus is growing so quickly that there is a big difference in size from week to week. However, the accuracy of the ultrasound examination is always dependent on the skill of the sonographer and the quality of the equipment. The EDD from the early dating scan is used – if the last menstrual period is not known or is unreliable, or the dating scan differs from the last menstrual period dating by more than 5 days.

Ultrasound examinations from 12 to 22 weeks are regarded as being within 10 days of accuracy or up to 10 days earlier or 10 days later than the woman’s calculated due date. Ultrasounds performed after 22 weeks gestation cannot be used to estimate the due date of the baby because the size no longer reflects the age very well. Even average babies can differ by up to 2 to 3 “weeks of growth”;.

Typically, the start date is the first date of the menstrual cycle, adjusted two weeks out to get the estimated ovulation date. The reason is that most women who get pregnant without IVF are not tracking their ovulation the way you would in an IVF cycle. Because of this, doctors make estimates based on information about the last period.

Why a IVF Due Date Calculator is important
