Is slight pinkish discharge normal during early pregnancy?
A slight pinkish discharge can be normal during early pregnancy as it can be the time in which the fertilized egg attaches itself to the uterine wall.
It can also be cervical polyp. A cervical polyp is a harmless growth on the cervix and can cause bleeding during pregnancy due to increased estrogen levels; because there are an increased number of blood vessels in the tissue surrounding the cervix during this time, it can cause bleeding if contact is made in this area during sex or a cervical exam.
However, it may not be normal for you so always consult your doctor.
