As for irregularities. There was a time I didn’t get my period for a year. Another time 9 months. My GYN prescribed progesterone to help get it going when that happens again. Though I never tried it because I completely changed my diet and became more active and haven’t had that issue since. Diet change is hard, but because I’ve developed severe GI issues I didn’t have much of a choice. But I noticed of course stopping eating fast food helped tremendously. I eat low FODMAP for the most part and generally eat little red meat, no/low gluten, no dairy, soy free, and just drink water. I go for an hour walk just about everyday sometimes 2 hours if I’m with a friend. I lost 50 pounds and it’s helped a lot as my skin and periods did mellow out. I also take multivitamins to help with energy.
