Anyone else having these issues?

Sarah

I absolutely love water!!!! So drinking it has never been an issue, but today I can't eat and can't even keep water down, I drink it slow and boom it all comes right back up! Anyone else!? I also have a ranging headache 😫 (2 days now) my mouth is constantly watering! This is my 4th pregnancy and I've never had this issue with my other pregnancies. I also finally took a poo today (sorry TMI) and it was black and tarry with a horrible smell and of course I Googled and that has me worried now... any advice is appreciated 💕
