Advice?

Ch
Mm. So this past week or two I've been feeling so nauseous. After I eat or drink anything like I just feel weird and I'm not sure why? I've also been feeling kind of anxious. 
My period was also weird, I had it for only two and a half days and it was SO light. Never been as light as it was. 
I'm not sure if those are even connected but does anyone have any idea is being nauseated could be linked to my cycle or whatever? Is it even worth checking out? I just really don't want to go to the doctors unless like it is, because money and all that and I'm a broke college girl. 😅😅
