I am new to this page so I am just coming across this. I have been obese since middle school, and probably morbidly obese since high school. I started my cycle SUPER late, like around 18y/o and if was completely irregular. I would have it for 3 weeks, then not again for 3 months, then have it for months regularly and again with the irregular. Then I just completely stopped having it, for years. I never cared so I never said anything to my OB or DR. I mean who wants a period anyway? But then at a yearly visit I had "bad cells" with the potential of cancer. So then it came up during questioning that I don't have my cycle and I need to because that is what flushes the "bad cells" from building up and potentially causing cancer. BLAH BLAH BLAH.. long story (kinda) short, I lost 120lbs and started my having my cycle regularly naturally. Even when gaining it back and loosing it again and gaining it back AGAIN I am still very regular with my cycle. I keep hoping that the WLS does not mess it all up and give me mega periods or something crazy.
