In labor??? Advice

Hey everyone, 2nd time mom but was induced early with the first so haven’t actually went into labor on my own yet. I’m currently 39+4.

About an hour ago I went from cooking dinner to immediately feeling awful: very nauseated, hot flashes, sweating, back pain..and then explosive vomit followed shortly by so much diarrhea (sorry tmi). All of this occurred within a matter of 20 minutes.

Since then, I’ve been laying on my bed and have been trying to time contractions but it’s so hard for me to differentiate the pain of my stomach tightening from him moving inside with regular stomach contractions. Definitely still feeling a lot of back pain while laying here. Almost constant like back spasms. I feel though that if I am having actual contractions that they’re 4-6 minutes apart..that is if they’re true contractions. I guess I’m just laying around and hoping my water breaks as a true sign or until I can’t breathe thru the pain anymore. Hospital is 45 mins away though and still would need to coordinate what’s going on with my 4 year old. Ugh..I hate this phase 😩 Just want a sure sign.

Anyone have labor start for them like this?
