Anyone else experience severe PMS symptoms?

So, strangely, I find that the week before my period is when I have the fewest symptoms. I actually feel normal that week! It’s the week or so following my period where I feel off. I told this to my doctor and she couldn’t quite explain it - just told me to be grateful that I have a week-ish in the month where I don’t have pain or other symptoms. All the symptoms you described could definitely be endo, especially if your pain levels are really bad.
