There is no necessary connection between a greater pregnancy response and the stability of the fetal embryo. A high reaction to pregnancy does not necessarily mean that the hormone level is much higher than that of a low reaction, but there is no direct connection between the two. There is a direct relationship between a high reaction to pregnancy and one’s own constitution, as well as subjective feelings. There is no direct link between the feeling that the embryo is well developed or not based on how big the reaction to pregnancy is. During this period, it is important to listen to the doctor’s instructions and have a regular maternity checkup. Blood will be drawn to see the hormone level and ultrasound will be done to see where the gestational sac itself is laid and if it is an ectopic pregnancy to be ruled out. After 45 days, you can also have an ultrasound to see how the embryo is developing and whether it has a fetal heart or not.
