40 weeks and 1 day. Possible contractions?

Since this morning I have been having lower back pain, mainly around the love handle region. Also been having mild to moderate cramping that comes and goes with a feeling of tightness in the very low abdominal area. Could this be the start of labour? Nothing is consistent but seems like it's almost constant. Just have an overall feeling of being unwell today. Tired, not very talkative, kinda depressed feeling. Any input would be appreciated. 🍁
