Any other ladies around 9 1/2 weeks getting worse cramps?

For the past few days I've been getting back pain, af cramps, sometimes quick stabby ones in cervix or just above public bone. Nothing terrible and it doesn't last more than a few seconds... it's just gotten more frequent and I'm starting to worry 😕 are you experiencing this too and is it just the baby getting bigger or?
