Weird period, spotting 2 days after?

It sounds like you may be experiencing some side effects from switching from one type of pill to another. They may have different hormones which will affect your body. Missing pills will also throw off your hormonal cycle. Did you miss the two BC pills in a row? There may be a chance of getting pregnant because of the unprotected , so you can also take a PG test to be sure. Headaches can also be caused by the hormonal changes. Four days in a row kinda stinks...sorry u r experiencing this. Call your doctor's office and speak to one of the nurses. They don't charge for phone advice and know a lot more about how the BC pills can affect your body. Good luck to you and take care.
