I am obsessed

I am 6w4D pregnant. I experienced two miscarriages last year. I test daily just to make sure lines are getting darker ( I know I shouldn’t) I suffer from anxiety and I have to wait until next week for my ultrasound. Everyday at night and during the morning my body feels really hot but I don’t temp. I really don’t have anything else other than sore breasts. Well, this morning My body didn’t feel as hot and my breast are sore but not so sore. Now, I am thinking of the worse. What is your temperature suppose to be when pregnant? And does that mean anything really? Please help. Thank you.
