Girlfriend started period again less than a week after stopping.

No, there is no concern of pregnancy. You might be thinking of implantation bleeding, which only about a third of women experience.  Implantation bleeding is vaginal discharge which usually contains a small amount of pinkish or brownish blood.

Glad to help. Your girlfriend is blessed to have a caring boyfriend like you:)

By taking Plan B so frequently, your girlfriend is causing potential harm to herself. Let me explain.

Most birth control pills contain synthetic forms of two female hormones, estrogen and progesterone. The controlled amounts of these hormones prevent pregnancy by stopping the release of an egg from an ovary (ovulation), thickening the cervical mucus and thinning the lining of the uterus. A woman gets a controlled period while taking the inactive pills, after she has taken 3 weeks of the active pills.

Now, Plan B is an emergency contraceptive and should only be taken in the event of a contraceptive failure.  If your girlfriend is taking her birth control pills regularly, there is no need to take Plan B, just to be safe.

Plan B contains levonorgestrel, the same ingredient found in many birth control pills. It uses a larger dose of levonorgestrel than in a single birth control pill.

By taking Plan B as frequently as she has, your girlfriend is overdosing on synthetic female hormones. It is no wonder that she is having such an abnormal menses experience.

I strongly suggest that she makes an appointment with her gynecologist to be evaluated.Please advise her not to take Plan B as a safety measure, there is no need.  I hope this information is helpful and eases your concerns.
