Irregular periods : Irregular periods are one of the most common problems obgyns treat. If this is one time problem it usually resolves on its own. If this is a recurring problem you should be evaluated. Infections & hormonal changes can cause spotting. If there is a concern for pregnancy then do a home pregnancy test . There are many options available to help regulate the menstrual cycle. Schedule a visit.

Needs sorting out: Make sure there is not still some pregnancy hormone in the blood - check hcg. If that is negative then need to ask whether the uterus lining (endometrium) can build up and have a menses: you can do this by giving estrogen and Progesterone (higher dose bcp's) for a 21 day pill pack and then stop. If again no menses then there is some concern regarding scarring of the uterus. Have your gyn pursue it.
