Crohn's and some of the meds that go with it can throw the hormones around. BC pills can cause spotting. You are a bit young to be having this problem. Since you had an ectopic pregnancy this year I would recommend you follow up with an OB/GYN and soon. Some months I have multiple periods and I am a moderate to severe case of Crohns, however, I am peri-menopausal.
