Well last night almost completely sucked

Before we go out trick or treating I always make sure the kids are fed with real food before they stock up on candy, so as usual we ate, about 10 mins outside I started getting bloated, at first I didn't think anything of it since I'm now 9 weeks pregnant figured something just didn't settle right, then I started getting cramps really bad, next thing I know I'm trying to run to the nearest bathroom around as soon as I get to the bathroom I had to grab the trash can and take it to the stall with me, I was literally spewing out both ends, I was in there for almost a half hour! Every time I got up I had to sit right back down. finally I got a release, caught up with my family and tried to finish trick or treating. It then hit again, I had to run back to my house and sit for another 20 mins on the toilet with cramps so bad I was crying. Luckily I didn't throw up just was dry heeving . It was a quarter til 9 and I was so upset I wasn't able to trick or treat with my kids I started crying worse. Finally my stomach let up enough for me to finish and we grabbed the car and took off to houses farther from our house and guess what, the girls got even more candy than what they got when I was in the bathroom lol

I felt so bad for my husband, he was exhausted from our wedding the day before, working almost 20 hours the day before that and 13 the day before that. Needless to say we all went to bed early last night.

I woke up the morning with a huge knot in my throat, rumbles in my tummy and nausea again. I'm just waiting for it to hit me like a ton of bricks again.

Any advise?
