37 weeks 4 days contractions gone?

I’ve had strong contractions for the past week and had BH for a month before that. This past week I’ve had pretty consistent period like cramping and I’m dilated to 3cm and 70% effaced. However, over the past day or so I’ve noticed that I don’t seem to be having ANYWHERE near the contractions was having. Baby is still moving but I’m not feeling any cramping really or stronger contractions. Occasionally I’ll notice my stomachs hard. Anyone ever taken a step back like this before?
