No symptoms anymore?

So according to my LMP I am 5 weeks today and for the past week my breast were very sore, I was exhausted and I was bloated and having some cramping but that's about it. But this morning I now feel no symptoms. Is this normal? I've had 3 miscarriages about 4 years ago but I am now with a new partner. I am terrified to miscarry again. Has anybody else experienced this but went on to have a happy, healthy 9 months??
