What's happening?

I started having contractions earlier today, they were fairly painful but Inconsistent and stopped after about an hour. I had a bath to help with my back ache (and because I was covered paint, can't be going to hospital like that) everything passed, I was a little crampy but fine. Ate some tea and have just been watching Netflix. My SO is out and said he would be back an hour ago. I've just started having pains again, kinda like contractions but my tummy doesn't feel tight. I really really need to use the bathroom but I just can't go and I feel so sick I'm not sure which way I should be on the toilet 😫 could I be in labour? I don't wanna ring my mum if it's another false alarm and I cannot get hold of my SO 😡
