Cramping and Stomach Tightness

I just want some reassurance for myself. So I’m not quite sure how far along I am (I’m guessing around 5-7 weeks have an ultrasound the 3rd of February and another appointment the 16th of January) but I was just wondering if around the 5-7 week range, if it’s ok that I feel my stomach is slightly tighter than usual and I have little tiny cramps that go away. The reason I’m asking is because I’ve had a previous pregnancy that ended in miscarriage and I want to make sure my little one is alright and thriving !! I just need some other opinions 🥰🥺
