If gynecological gel is used without knowledge of the pregnancy, it does not usually cause serious effects on the embryo. This is because gynecological gel is an intravaginal medication, which is a topical medication. It is only used topically and has very little effect on the body, so the effect on the embryo is also minimal. Because this medication is used in early pregnancy, it may cause spontaneous abortion if it has an effect on the embryo development. If there is no effect on the embryo, the embryo will continue to develop. If there is no abnormality in the ultrasound after the medication, it means that the effect of the gynecological gel on the fetus is minimal. However, it should be noted in the future that if there is any discomfort, you need to go to the hospital for examination first and then apply the medicine for treatment under the guidance of the doctor. If you use the medicine blindly during pregnancy, it may indeed affect the growth and development of the fetus, and may even cause fetal malformation or miscarriage, etc.
