[|Human|] My Girlfriend is Pregnant, and we went to planned parent to get the confermation, she said we were about 5 weeks, then last night she was not feeling well so I took her to the ER and her BETA level was 36 and they wanted to re-check her so we decided tonight to go and it went up to 64.11 They said she was only a few days pregnant? How is this possiable
[|AI|]  Hallow Dear, You can locate the duration of pregnancy by following ways:1. The egg release takes place 14 days before the next menses. It can roughly tell you the probable date of fertilization.2. Usually the period of pregnancy is counted from the first day of last menstrual period.3. Ultrasonography and Chat Doctor levels tell you the gestational period from the day of conception. Hence, there is a difference of about 2 weeks in the clinical gestational period and gestational period estimation by these investigations. When you are informed 5 weeks pregnancy, it refers to 5 weeks from last menstrual period; which actually is about 3 weeks from day of conception. This should clarify your dilemma.
