Impatient babies and wendys

So to start, I am due May 19th. A few days ago my husband and I got a full date night away from our toddler who was staying with his grandma. Anyone who already has a toddler understands the rarity! So we go to Wendy's to eat. Were having a great time. Well my hubby starts to not feel well and we head home. He ends up being okay and just wanting to sleep, however this is when I begin feeling sick. I'm not so lucky. I was up all night throwing up. Next morning I've gotten zero sleep and been throwing up every thirty mins and began to feel what I thought was braxton hicks. I take a bath do all the Normal "go away contractions" deal. Still happening still throwing up. My husbands making me drink tons of water and Gatorade and I'm steady throwing that up getting madder at him for making me drink anyway. So we head to l&d. I found out that i got food poisoning and the vomiting caused dehydration and pushed me into labor and I am now 1 cm dilated. The only reason I stayed one cm dilated and did not go further into labor was, you guessed it, my insistent husband. Can't live with him can't live without him. The problem is now anything can make me go back into labor especially since my son was a preemie as well. Wish me luck on keeping this one in the whole time.
