New pregnancy symptoms

I am currently between 3 to 5 weeks pregnant and I cannot get a stable body temperature. I'm either hot and sweating freezing cold. I think I might be pregnant with a dragon LOL. But I'm also having a very hard time sleeping and keeping my husband awake all night long. This is my first child his second we are very excited but also trying to take it one day at a time and not get over worried about what the future may hold. I was just curious as to other women who found out that they may be new mothers, what symptoms ya'll are having? I'm praying for us all and to those who are trying. With endometriosis and having to have cyst removed numerous times I was told it was very likely I could be pregnant and I've taken 3 test and the past 3 days that are all positive, God is good! If there any other ladies out there who's been told by a doctor they can't get pregnant don't listen to a man over the Creator you know your body best. There's always hope.
