Loss Of Some Symptoms?

I am 10+5 today and have noticed some of my symptoms disappear over the course of the past few days. I used to be nauseous most of the time and no longer feel that way. However I have been getting dizzy/lightheaded spells and my boobs are still tender to the touch as well as some constipation. My first was a miscarriage, and I'm just trying to make sure I don't miss anything that could be a sign of miscarriage again. I'm terrified it will happen again.
