Is this normal?

So I’ve have very light and intermittent cramping all week, but last night it became more consistent. I had very light spotting, brown in color but no bleeding. I was so uncomfortable last night until I finally fell asleep, and now this morning it’s an achy cramping and my back is killing me. I’m five and a half weeks along. Is this cramping normal and does anyone have any rememdies?? I am so uncomfortable 😣
