AM I IN LABOUR.....???!?!!!?!!?!!?

I'm having increadable back pain and an extremely tight pain(maybe that's not the word, but it's extremely uncomfortable pain) under my belly. I had sex a couple hours ago now and since I've laid down its began. I've also had a lot of energy the past two days which is weird for me because I've been overly tired the past month. I think I might be in labour but I really have no clue šŸ˜“
