So i was on the pill for 4 months only i finished the last pack and had my withdrawal bleed as you would 4 weeks later im waiting for my natural period and nothing yet. Im 4 days past my due date and today seen light spotting not normal for me. Had a bizzare month thing ive not been through before. 2 test come up negative. Why do you think this is happening is it normal to be late for your first natural cycle?
