Missed period? stress? idk

So I'm in a tough time time right now. I'm right in the middle of moving. I missed my period last month and this morning about an hour after I woke up I puked. And last night when my bf was cooking I had a lot of nausea. I really hope this is all in my head. When I was younger I would sometimes miss my period for six month. But ever since I turned 18 they have been pretty regular. I have been in a lot stressful situations than that since then. And I don't believe I've missed a period since then. I didn't know who else to share this too so I'm sharing it here.
