Cramps and pains

Rachelle • Mother to 3 daughters and 3 sons. Mother to 3 angels taken early in pregnancy. Currently pregnant with my number 7.
I'm 16+2 weeks and since yesterday have had constant pains in my lower belly and into my hips and thighs. It kept me awake all night and are strong this morning. No bleeding or spotting. Should I be worried. I'm thinking I need to go to the dr to check things out.
