I get my periods naturally now since going paleo/primal. I don't have to take bc pills anymore in order to have a period. I'm 31, and have never had a regular cycle. I got my period twice a year, if that, lasting for 10-14 days. Some years I only got it once, or not at all. I was told it would be this way for the rest of my life and that I'd be on hormones for that long as well.
Since most of my periods were artificial or torturous, I am now trying to get used to the idea of menstruating every 28 days or so since I never have over the past 18 years. I can start to predict when I am ovulating due to various feelings and behaviors - aggression, exercising more, eating a lot more, that pimple that just has to show up, and other things, like more male attention. Being fat before, I was invisible to men anyway, but even though I'm not now, if I know my period is due by calendar and a guy is paying more attention to me, then it's probable I am ovulating because I'm sending out the signals. I use a Diva Cup since tampons are kind of icky and expensive in this country. That, and you have to throw them away. At work, we don't have staff bathrooms so I am apprehensive about throwing pads or tampons away in the bin in the same bathroom stalls that the kindergarteners use or having to leave class to change them. This way, I change it in the morning, when I go home for lunch and when I come home from work and before I go to bed.
When I get my period, I am bloated for a day but my skin clears up. My periods have been getting lighter since they've come in regularly - at first, they were five days, then four, then three with some light spotting. No cramps, no clotting, no having to call in sick being doubled over in pain unable to walk. I do get more sleepy but nothing unmanageable. I also stop feeling aggressive when I have my period. Other symptoms are starting to lessen, like breast tenderness, backaches and constipation as time goes on.
