As we get older, our periods changes, sometimes for the better, sometimes not. Having a baby too, helps these changes along. Now Im not saying that you cant be pregnant, however I have had periods like that from time to time, when I am usually have a heavy, 7 day period. For me, I was 28 days to the sec before I went on the pill, before we had our first kid, then after I went off, it went every 34 days or longer. Now I have either 28 or 34 days. lol Its still heavy, usually. It really does depend on how you feel, stress out, or relax. lol I have had a period when I was pregnant with my third baby. I thought I was miscarrying, since I had already knew that I was pregnant. Luckily for me, she hung on and I have a wonderful little girl to show for it. My mom had 2 or 3 periods during her pregnancy with me and I am going to 34 this year. If you suspect that you are pregnant, then when its all over, get a test and found out. Good Luck!
