Labor?

Hey mamas! So wondering if maybe im starting labor and not noticing it? Yesterday and today ive had nausea/vomiting. Extra pooping the last couple days. Had some strong contractions this morning but seem to have gone away or maybe im not noticing them as much since im out of bed now for the day. I do feel some tightening occasionally but not sure its actual contractions? Wondering if this is something a mom has experienced previously and did go in to labor?
