Another side effect you will also experience is heavy vaginal bleeding which will last for a few weeks, sometimes up to a month after the abortion. The length of time you bleed will depend on a number of factors from how many weeks pregnant you were to you as an individual. Sometimes you may find clots in the bleeding which is perfectly normal but if they appear regularly and you are bleeding excessively you should seek medical help from either the clinic you went to or your GP. Excessive bleeding is when you are bleeding so heavily that you soak more than two sanitary towels every hour for a couple of hours in a row
