If the fibroid is small in size, pregnancy will have less effect on the fetus and may not even affect the development of the fetus, but if the fibroid is large in size, pregnancy may affect the development of the fetus. In case of subplasma fibroids, the size of fibroids is small, the patient does not have obvious discomfort symptoms, and the location of fibroids does not affect the embryo’s implantation, nor does it affect the embryo’s blood circulation, the pregnancy of such patients will have less effect on the fetus, and may not even affect the development of the fetus. Due to the large size of uterine fibroids, it may lead to make the embryonic disk attached to the fibroids, which may affect the blood circulation of the embryo, and then affect the growth and development of the embryo, resulting in the embryo in the uterus, such as developmental delays, at the same time, fibroids will also occupy the internal space of the uterus, and with the development of the embryo, it may limit the growth of the embryo, so at this time, uterine fibroids may affect the development of the fetus. Women with uterine fibroids should undergo systematic treatment under the guidance of a doctor, and undergo obstetric checkups on time after pregnancy to observe whether the growth and development of the fetus is normal or not in a timely manner.
