Really need advice please!

Hi all, I’ve just emailed my doctor about this but I wanted to see if anyone had experience with sever morning sickness in the meantime.

I’m about 5 weeks 6 days. I’ve had nausea on and off for the last week, but within the last 24 hours I can’t keep any food down, I can’t sleep, and I can barely handle liquids. My uterus is tight and sensitive to touch. I am literally on my back unable to really function. I’m also a bit light headed simply because I haven’t been able to give my body nutrients. I’m constantly nauseous now-no breaks. No fever, but constipation.

Would you guys suggest going to the ER today (Sunday)? I don’t want to overreact but I don’t feel right at all.

Please, any advice, experience, or input will help.
