Pain on left side?!

5 weeks and 2 days pregnant
I have a very hard, dull, cramping, on my left side close to my ovary. The pain extends a little into my thigh and lower back. It's not excruciating, but it kind of feels like the sciatica I had when I had my first child. Anyone have this feeling early in pregnancy?  Paranoid a little after TTC for two years after my miscarriage.
