Normal or not normal?

Abigail

I am 34 weeks and 2 days. I went to the dr yesterday for a checkup and I was fine. Yesterday evening I was uncomfortable, pain in my mid belly to the top, tightening in my belly, back was killing me. I was really tired. I went to bed about 8, woke up at midnight with back pain, went back to sleep 30 minutes later and woke up this morning about 7:30 and still feeling the same thing happening.

Is this normal at 34 weeks?
