Cramping at night waking you up

Des

I am almost 6 weeks and have had an ultrasound and they seen the sac. But I feel like the cramping I’m having can’t be normal. It will wake me up in the middle of the night. It’s usually in the middle of my stomach. Anyone else have this? I’m not sure if I am just being a baby cuz for the last 8 years I’ve been on birth control to not have a period so I am not used to cramps at all.
