Feel like I'm gonna lose it from both ends

Sorry if this is TMI but I'm 14 weeks exactly today. This is my first pregnancy. In the beginning I got nausea spells but never really felt like I was gonna vomit until a few weeks ago. It first happens a couple of times when I was in the shower. I felt really light headed so I thought maybe the water was just too warm and I was in there too long and that's why I felt like I was going to vomit but just an hour ago I was making breakfast for my boyfriend and I and I felt it again. Got light headed and felt like I was going to vomit. But every time this happens I also get the feeling like I have to poop at the same time. So I use the bathroom and that helps a little but I still feel like I'm going to puke until I lay down. Has this happened to anyone else or am I just weird lol
