Lets talk pre-term labor

Quiena

So I had my first non stress test the other day and it didn’t go well. 5 contractions in 30 mins. I was put on a day of bedrest. Today I’ve been getting some back pain and feeling a lot of baby pushing down. Tomorrow I’ll be 36 weeks. Should I be overly worried? Baby is moving around ok. No water break or leakage. This is my second kid but the first time was nothing like this. Is this pretty standard?
