I am 18 years old and I am experiencing something unusual for me. My period ended 2 weeks ago and after 2 days it started again but this time what came out was slimy red discharge and sometimes just white discharge. I tried taking antibiotics thinking it was just an infection but when I took the antibiotic the discharge turned to greenish/yellowish color. I stopped the antibiotic and I am cramping again with blood like I would normally have during my menstrual cycle. What is going on? I would really appreciate to know. Thank you.
