1 UlcerOnTopAnother: To make an intelligent answer it would be necessary to know what antibiotics and what doses and any other meds you take. Some antibiotics are known to alter the period but it's a rare occurrence and usually not severe. But it may be something else. I wouldn't stress over it unless it recurs for, say, 3 months in a row or other symptoms develop. And make sure you're not pregnant with a urine test.

Stress?: Your menstrual cycle is controlled by a delicate balance of hormones secreted by your brain and pituitary gland. Unusual physical or mental stress or concurrent illness can alter this balance and cause an abnormal cycle.
