Is pregnant 45 days ectopic pregnancy symptom?

As we all know, the hCG of women who are not pregnant is 0, and the hCG is greater than 10 after pregnancy. If the embryo development is normal, hCG will increase with the number of days of embryo development. Under normal circumstances, hCG will double every two days and increase regularly. Of course, this speed is not absolute, hCG will vary from person to person. In other words, the hCG of some embryos increased by 66% every two days; In some embryos, hCG is doubled every two days. No matter which multiple hCG grows, its growth rate cannot be lower than 66%.

The embryo is 45 days pregnant, that is to say, the gestational sac has been formed, the embryo bud and fetal heart may still be waiting. The formation time of gestational sac is within 30-40 days of embryo development, while the formation time of embryo bud is within 40-50 days of embryo development, and the formation time of fetal heart is within 50-60 days of embryo development. At present, the embryo is only 45 days old. Normally, it will form a gestational sac. However, hCG only doubled in a week, which was very low and abnormal. In other words, the fertilized egg may be implanted outside the uterine cavity.

HCG greater than 10 can be determined to have been pregnant, but can not be determined to be intrauterine pregnancy or ectopic pregnancy. If the gestational sac can be formed on the 30th to 40th day of pregnancy, then ectopic pregnancy can also be ruled out. But now only 45 days of pregnancy, hCG only doubled a week, so it can be inferred that this is ectopic pregnancy. HCG value of ectopic pregnancy will also increase, but the growth rate is slow, and there is no regularity. The growth rate of ectopic pregnancy is generally lower than 66%.
