I've been feeling crampy and mega bloated for the past week

And today everytime I take a really deep breath the pain is there and has been for a week ish somedays I don't notice it but today it's sore just like a few days after you've been to the gym and worked on your abs and it's on my left side, I've never felt this pain previous months and I thought I'd have a bath and see if that works but it hasn't it's like I have a constant stitch? Anyone had this and they were pregnant??

I'm due my period between 11th and 13th but as I said before I've never experienced this before
