7 weeks pregnant and having light cramps

Lorriane
I'm 7 weeks pregnant I went to the doctor last Wednesday and they told me everything is fine and my baby's heartbeat is very good as well but today I'm having small light twinging cramps on my left side of my abdomen and sometimes on my right side and I don't feel pregnant I have not had morning sickness or anything like that has anybody else gone through this? Its kind of making me worried I could really use some good advice.
