1. Can I have sex when I am three months pregnant? ——Understand the safety of early pregnancy. Three months of pregnancy refers to 9-12 weeks of gestation. At this stage, the fetus has formed complete organs, but is still in the development stage. Therefore, you need to pay attention to some safety issues when having sex. First of all, since the fetus is not fully mature and the neck opening is not completely closed, it is necessary to avoid overstimulation or use of excessive force during intercourse. At the same time, avoid using chemicals such as lubricants during intercourse to avoid adverse effects on the fetus. Secondly, in the early stages of pregnancy, because the embryo is smaller and softer, it is more susceptible to external stress.
