Contractions ?

Bi

Im 39+2 I lost my mucus plug last Wednesday and yesterday I had light spotting with more mucus. I began to feel heavy cramp like sensation since 3:00am and have been getting them 1 or 2 every hour. They last about 15-30 seconds each. Has anyone experience anything similar if so are they real contractions or false? Should I wait to go to the hospital... feeling nervous 😬
