I'm at a loss (36F)

I'm a 36 year old female and at a loss. long story short. I've been relatively healthy my entire life, however, after I gave birth, I suddenly developed the most random things. first, I was pumped full of pitocin during labor, and had retained products of conception in me for nearly ten weeks after birth. my blood pressure shot through the roof (I've never had high blood pressure), and even with medication now, it still runs high on the diastolic number. I stopped sweating in most areas of my body. half of my forehead is permanently red, and I have poor heat intolerance. I now get ice pick headaches. my ANA came back abnormal, my ANA titer is abnormal, my c reactive protein came back abnormal, my westergen test came back abnormal, but all further testing for autoimmune disorders came back normal. I've been to multiple doctors who tend to sweep my concerns under the rug and tell me, "your body changes after birth". I know something isn't right, but I don't know where else to go or what else to do. any insight would be amazing.
