I had a somewhat of a period this month and it was very irregular. The first day it was very light to know bleeding ( when usually its heavy for 3 days straight, then gets light as the days go on. My period last 6 to 7 days every month), then the next day is was semi regular then it was faint the next 2 days. It lasted for a total of 4 days. I was on antibotics for my wisdom teeth being abstracted and I thought that could be the cause of the irregular period. I am not sure and I am freaking out! I have very crazy periods its not like clock work like everyone elses. I guess it falls between 25 - 27 days apart. Last night I felt bloating like cramps, but no bleeding. The pain kind of started on the side and moved all the way around my back. I have no tenderness in my breast, but I feel sick to my stomach or I have no appetite sometimes. Could this be my nerves? Could I be insane????
