The simple answer is no. However some women can experience false periods, also known as decidual bleeding, which resemble the consistancy and regularity of a period for the first few months, or even the entire length of pregnancy.
Before you read any further, please be aware that you should always check with your doctor if you are experiencing any type of bleeding during pregnancy. A lot of pregnancy bleeding is benign but some pregnancy bleeding can be a sign of a miscarriage or issues with your placenta, too.
The technical stuff: After ovulation, if the egg is not fertilised, your body sends signals for your hormone levels to drop and the internal lining of the uterus is shed in menstruation. If the egg is fertilised, then your body sends signals for the hormone levels to increase, instead of drop. However if your hormones get out of wack, sometimes your uterus can shed some of the lining of the uterus, which can cause decidual bleeding. It’s more common in the first few months of pregnancy, before the placenta implants into the uterine wall, but some women experience it throughout pregnancy. Scientists are still unsure what causes decidual bleeding in pregnancy, but in most cases it doesn’t seem to have any adverse effects on mother or baby.1 | 2
