I’m nervous

I’m 5 weeks pregnant. This is my first pregnancy. My husband and I are both very excited.

But I am worried about how I am feeling. I have cramps through out the day. In my sides and back and my tummy. No bleeding though. I feel bloated. My breasts hurt so bad. I get dizzy spells once a day. I have had a few headaches. I’m tired all the time. I get nauseous on and off all day. I just feel so crappy. I’m guessing wondering is this normal way to feel at 5 weeks? I just feel lonely in this. My husband is very helpful but not sure either.
