Is cramping normal at 4/5 weeks?

Tasha

I'm currently 4 weeks and 5 days pregnant, I've had bad heartburn and some crazy emotions, today I cried because my husband wanted to take me to breakfast and I didn't want to go, then cried because my hair was too fluffy, then later cried because I was tired of crying. I've been cramping fairly bad to, but usually not as bad as my normal period cramps. I guess I'm just concerned about the cramping and if it's normal. I usually have small cramps throughout the day off and on, but at night when I try to sleep as soon as I lay down I'll start cramping fairly consistently. If I lay on my left side it's worse than my right and if I lay on my back with my head and shoulders elevated it usually stops. Is this normal? Just trying to get some info, this is our first so I'm new to all this. From what I've read it's normal as long as no bleeding and the pain isn't super intense. TIA for any opinions.
