So about a month and a half ago k had to take a plan b:(  totally messed up my cycle and of course I had a period about 5 days after I took it. Then I skipped a month... My period was late for exactly 30 days and then I get a notification from <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> that said to stock up on chocolate, so I did and what do you know period came today. I thought I would be irregular because of the plan b which is super weird?
