So yes, I was sterilized in 2016. I've tracked my periods since I had my last baby in 2014 so I know (or thought I knew) my cycle pretty well. My cycles are around 26/27 days long but sometimes do like to surprise me and come early. Anywhere between 22-29 (29 not very often though) is how it's gone for the past four years. So here I am now, on day 33 and driving my self nuts. Just clear it up, I would loooooove to have another baby. I've been researching as much as I can about anovulation, hormone imbalances, sterilization failure rates but can't seem to get any clear cut answers and I'm not ready to have my wishful thinking snatched from me yet. Anyone had similar experiences with random late periods?
