Dear friends, I have always had the problem of irregular periods. But for the past few months they became regular, and now I can be confident when I'm going to have my next period!! The only change I think is drinking coffee every morning. I never used to have coffee/tea earlier, and even now I don't crave for coffee. Since the past 6 months I am going to office really early (7.30 in the morning), and to keep me awake and give my mind a kick, I have started drinking coffee in office (just half a cup of coffee and little cream). I don't have coffee or tea or milk any other time of the day. Now, I'm really wondering if it is coffee that is making my periods regular?!?! I have not changed my eating habits or lifestyle, no worries/tensions, no anxiety or mood changes. But all of a sudden since the past 6-7 months my periods are regular!!!
