I’m in my mid-late 30s. Have very regular periods, but always get hot at the same time (3am) the night after I ovulate and then as I near the end of my cycle. I was on birth control all through my 20s/early 30s and don’t remember it happening until I was on my own cycle (and subsequently went through multiple rounds of ivf). Is this an indicator of entering peri-menopause, or something that can just be a part of normal pms for some? (Or triggered by multiple cycles of hormone based fertility treatments?)
