Bleeding after sex during pregnancy
I am 34 weeks pregnant with my first baby. When I had sex with my boyfriend I started to bleed soon afterwards. I didn't feel any pain or changes in my body, but I am worried because there was a lot of blood. My doctor told me that my uterus is open and gave me antibiotics to help prevent infections. Please can you give me more information about my situation? My paranoia is running away with me.
Dr Bronwyn Moore (gynaecologist) answers:
Bleeding in pregnancy is not uncommon, it can happen can happen at any stage and can have many causes. Sex during pregnancy is generally not a problem unless you have a low-lying placenta, your cervix is short or if you are at risk for preterm labour, then your doctor may advise against it.
The most common reason for bleeding after intercourse is that the cervix becomes very vascular and soft during pregnancy. The surface of the cervix is very soft and any pressure on it can cause contact bleeding.
