Really worried/anxious. Is baby okay?

Hi all. I have many helaht issues just to give a background. APS, Uctd, fibromyalgia etc.

I'm 15 weeks pregnant and have been so poorly with this pregnancy, with the usual pregnancy symptoms and some extra due to my auto imunen diseases.

I have been so so itchy for over a month now all over my body, specially back, neck, arms and head and gets worse at night to the point I wake up wanting to rip my skin off. I've been to the Dr a month ago and they gave my steroid ointment for my scalp as my follicles looked inflamed and a cream for the rest of my body which I googled is used for bacterial infections. So now I've been to the Dr's again yesterday, symptoms are itching, constant Headaches, extreme fatigue and if I walk for more than 10 mins I start to get really bad cramps and back pain so I'm resting alot, problem is some of these symptoms might be over lapping with the other illnesses and not to mention the other small litlle symptoms.

Drs is suspecting collestasis, or under active thyroid, or anemia. So had my bloods taken and now just a waiting game. I'm worried as all the research I've done on collestasis is people who have developed it after 27+ weeks and I'm only 15 weeks and have been like this probably since 9ish weeks. Anyone have experience with the above or their own or someone elses story to share with me please? I'm so anxious.
