That doesn't sound supper normal it may be. Look it up online or call a nurse hotline to be safe. Sorry you're dealing with that.:(
With this pregnancy the first time I threw up was week 14 and it was green with mucus and a lil blood. But I had just woken up and had an empty stomach. It could just be your stomach acid. I never mentioned it to my doc cus I don't think it was something to be to concerned about (the blood was because I was having a really hard time getting it all out) it could just be stomach acid from an empty stomach or if you're concerned call your doc. But I would say its normal and yo u should and baby should be alright. Good luck.
