I have been on Loestrin 30 for about a year after switching from a lower dose pill. I used to get normal, heavy period still. Heavy enough to bleed through a tampon. But recently, I have not really been getting a period at all. This has been the case for my last cycle and current one. It is more of a extremely light brown discharge. Barely one at all. Should I be worried or is this my body just getting used to the high dosage pill?
