Masturbation in early pregnancy is definitely not good. In early pregnancy, that is, the first three months of pregnancy, the placenta has not yet formed, so the relationship between the embryonic tissue and the uterine wall is not particularly close. If the patient masturbates too hard, it may stimulate the patient’s cervix, thus causing the patient’s uterus to contract and miscarriage. If the patient masturbates to orgasm, the patient’s whole body muscle spasms at the same time may also cause uterine contractions, so it may also lead to the patient to have a miscarriage. The patient’s vaginal resistance is relatively low in the early stages of pregnancy, if you do not pay attention to hygiene when masturbating, it is likely to cause infection, leading to vaginal inflammation, cervical inflammation. If these inflammations cause pelvic inflammation by upstream infection, it is very likely that the embryo will stop developing.
