I just found out that BC pills can mess up your cycle for months after use. Panicking! I only tried the Pill for one month. Do you think I should still expect irregular periods for the next few months? I was pretty regular before. I just tried the Pill to see if I had any side effects. I was planning to start taking it again with my August period, because I will need it in Sept. What if I don't get an August period? Also, it's my first Placebo Week, Day 2. When should I expect to have the withdrawal bleed? Thanks.
