Hormone Imbalance

I've had hormone issues since I was about 16. Had the tests, had the surgery couldnt find anything. In the end I gave up, mainly because my dad got ill but i also ended up getting pregnant.

Nothing went away during pregnancy, it was the hardest thing ive ever had to go through in my life. Had hyperemesis, cholestasis, so much pain etc.

My sons now over 1 and i feel like im all over the place. I want attention constantly, i want my partner in bed (which im not usually up for since having our son tbh), im crying all the time, im feeling irritated and the periods are all over the place. I lost weight in my pregnancy and cant seem to put on or lose more. I either feel really horny or really sad😂😭

I think I may have a hormonal imbalance, because i just dont feel okay in myself right now. Is it doctor worthy? If it is how do i word it? I dont want to come across like a know it all.
