Is it normal to have brownish discharge after intercourse during first trimester of pregnancy? *worried*

Pregnancy Sex. Some brown discharge (which is generally old blood) can occasionally occur after intercourse. A subchorionic hemorrhage is sometimes the culprit. There can even be some spotting as the uterus/cervix has a large blood supply with pregnancy and the exterior of the cervix can be fragile. Discuss this with your OB and have an exam and ultrasound to try to find the cause. .
