The only shitty thing I have read is this:
During the first CBC treatment cycle, about one in three women may have 20 or more days of unplanned bleeding or spotting (bleeding when you are taking pink pills). This bleeding or spotting tends to decrease during later cycles
But I think thats the case with all types of BC that makes you not have a monthly period.
You know I would LOVE to not have a period BUT they say if you want to have anymore kids these types of birthcontrol and shots that make you not have a period for months will make it that much harder to have a baby. I dont want to have to TTC for years
