Birth control making me sick??

I'm not sure if my birth control is to blame or if it's some sort of stomach bug.

It started on day 2 of taking my pill I was so extremely sick on my stomach everything I put in my mouth made me feel like I was going to vomit. Day 3(yesterday) I felt pretty much better until last night..I can't really describe the feeling..I just felt..sick. not really like throw up sick or use the bathroom sick.. I just felt blah. Now this morning I have a terrible stomach ache and diarrhea.

On day 1 of my pill my fiance noted feeling a little sick but he has normal stomach issues so when he's got an upset stomach we don't really connect any dots to a bug. Day 2 he felt sick again but he said it wasn't like mine where I couldn't eat without vomiting. Day 3 he didn't mention any stomach ache. This morning he had a "just sick" feeling.

Since he's experiencing sickness.. is this likely a bug?? I'm just nervous. One symptom in my packet says "if you are experiencing a bad stomach ache to stop taking the pill" I don't know if this is a bug or my pill :( I know yall don't either.. but advice ???
