Feeling sick

I’m 7 weeks and one day. Yesterday I had a great day but towards the end around 2am I thought I was hungry so I ate a bowl of cereal and after my stomach was really hurting and after moving around in the kitchen nausea was so bad and felt like needing to throw up it took so long but finally I had the urge but nothing was coming up after twice of trying on my own the third time my body attempts a tiny amount of the cereal came up my heart rate went to 130 And after I relaxed on couch drinking cold water I still had a heart rate of 115. My temperature read at 99.1. I went to sleep on the couch and This morning I woke up drank 32 oz water and pee literally about 7 times and I had two bowel movements all green. My stomach was been hurting in waves so bad with everything I try to eat I only feel okay if I’m asleep. I woke up to drink a blueberry banana smoothie and I got it down but my stomach still hurts and it’s not cramps. Anyone else felt like this. Stomach bug?
