Worrying myself sick. Symptoms coming and going.

I am 5 weeks and 4days and the last few days I have started feeling nauseous, my boobs were hurting and I was tired beyond belief. However this morning I woke up and I feel absolutely fine, like I’m not even pregnant. I’ve had multiple miscarriages and it’s worrying me beyond belief.

How can I have symptoms and then they disappear. Is this I’m normal? Should I expect another miscarriage in the next few days? 😭
