Perimenopause

Hi, this is my first time posting on here. I'm 38 years old, I have a 15 1/2 year old son, and I'm less than 2 months away from getting married again. However, the past several months I have been experiencing hair thinning, trouble losing weight, unexplained weight gain, mood swings, trouble sleeping, super light period this month or just spotting and not an actual period and not necessarily hot flashes but been hot and hot to the touch periodically and not when I was supposed to be ovulating. My whole life my body has been like clockwork when it comes to my cycle. Every month I start between day 28 and day 30, I feel the tiny pelvic pain in my ovaries, and I'm hot to the touch, between days 10 and 14, but every month on one of those days is when I feel the small cramp like dull dagger pinchy pain from ovulating. Anyway, every month it has ALWAYS been like clockwork until a few months ago. I'm freaking out, and I already have a doctor's appointment scheduled. Does anyone have any information or advice on this? I'm about to get married again, and we want more kids especially kids together. 😥
