What happens to you if you take plan B (Morning after pill) two times approx. 3 months?

I have been having weird (very mild) radiating pains since I've taken plan b for the second time. Likewise, my period that I got approximately 3 days after taking the pill was out-of-this-world heavy. I have a million and one good reasons not to go to the doctor at this very moment.... I should be able to go in about March-April time frame, with hopes (being a little dramatic I guess) that it's not life threatening (Ovarian cysts)
