You might want to read the book "Take Charge of Your Fertility". It has all kinds of information on cycles, getting pregnant, menopause, etc. It is very informative and might be able to answer some of your questions. I can't recall the author right now and I loaned it to a friend, so I can't check, but if you google the title it will come up. I know the mini pill really messed me up after the birth of my first child and I refused to take it after the second, but by now things should be more normal for you. If it is that bad, you may want to make an appt with your ob/gyn for a checkup and just to get your questions answered. They can also check your hormone levels and tell you if you are perimenopausal or not. Good luck.
