As mentioned above, the cervix becomes more vascular in normal pregnancy and also the glandular tissue of the cervix which has a tendency to bleed tends to pout out and point more towards the vagina during a normal pregnancy. For this reason, light spotting or bleeding after intercourse is particularly common. However, it is important to make sure that there is no other cause for bleeding following intercourse and you should always let your treating obstetrician know when you having bleeding following intercourse so other potential causes for this bleeding can be excluded.
