I'm currently on cd33. This is the longest my cycle has ever been. I've done a few hpts, all -tive. My bbt chart shows no sign of ovulation, with pretty inconsistent temps despite me taking it at the same time every day. What I want to know is how long these cycles generally last. I had a very early miscarriage in December and since then I feel like my periods have been a bit out of sync. Last month was a nice normal 27 days so I thought perhaps my cycles had settled. WRONG!! Has anyone else suffered this? Is it something I should worry about?
