12 weeks 6 days

And have been having the lightest amount of random cramps. Almost just a sharp pain in my uterus and then it’s gone. This is very worrisome to me as I have had a miscarriage in the past. I have no spotting whatsoever so I’m wondering if this is normal. I had period cramps up until 9 weeks and they had stopped but the past few days I have noticed this new pain I am having. Please give me advice!
