so confusing!!!

I've been losing weight which made me more regular ( average 90 days down to 43 last time!) and I never have a clue when I ovulate. I'm currently on CD 24 and have been feeling weird since Friday. I usually don't have any symotoms until like a day before af, but the last week my boobs have been sore, I've been an emotional mess, on and off upset stomach, and my lower back has been achy. I also totally fell off my diet so I'm trying to figure out what's what. I don't know if anyone has any insight, but I just wanted to get it out and vent about how confusing this is!
