Cramping early first trimester?

Angie

So I am almost 6 weeks. This is my third pregnancy but the first in about six years. I've also had a miscarriage before. Anyway, everyday since before I found out I was pregnant I get these bursts of cramping for a short period of time. They feel like a lighter version of my period cramps. Sometimes they are random and sometimes they happen when I get angry. I get them everyday. Sometimes I get the cramps only once a day or sometimes it happens more than once day. Is it normal? As this happened to anyone who did not have a miscarriage?
