In addition, your OB/GYN will likely advise you to avoid sex:
• if you have already had any heavy bleeding during this pregnancy;
• if the placenta is at a low level, which can be determined by ultrasound examination;
• if you have previously had miscarriages or premature births;
• if there are signs of a threat of miscarriage;
• in case of multiple pregnancy:
• for isthmic-cervical insufficiency;
• if there are signs of inflammatory diseases.
In this case, there is a risk of complications, and therefore it is better to take a forced break from sex for a favorable pregnancy outcome for the period that the doctor recommends to you.
Often couples are looking for an answer to the question of which position is more appropriate to have sex during pregnancy. As for the first and second trimesters, there are no restrictions, it all depends on the preference of the couple. But in the later stages, it is recommended to refrain from sex in a position when the woman is on her back, since the enlarged uterus begins to put pressure on the blood vessels, leading to hypoxia, as well as in a position when the woman is on top, since it requires more physical activity from her load and less comfortable due to a large belly. Poses on the side or the man from behind are better; for additional comfort, you can place a pillow under the chest.
At the same time, a woman needs to listen to her feelings and desires, and if something bothers her, she should consult her doctor for advice.
