Am I in labour?!

Natalia

I’m 38+ 3 today and I had sex earlier today at around 7pm (I think) I’ve been having cramps and back pain coming in waves... it’s been happening for the last 3-4 hours and it comes and goes. It’s not necessarily painful but very sore and uncomfortable. Am I going into labour or is this nothing to worry about? I’m a little bit panicky as I don’t want to ignore it if it’s serious or something?? Helpppp!!!!
