My cycle's finally driven me crazy. Up until I had my paragard inserted 2 years ago, I had 28 day cycles like clockwork. For about 6months after I had 32 day cycles and since then it's a crapchute between 32 days and 28 days. It's never any other number of days - just either 32 or 28, which I think is more crazy than having no regularity at all. My body seems to pick at whim which one it'll have a go at (ex April-32, may-32, June-28). Is there any explanation for my fickle cycle?
