I am have question now

:ermm: I know how things work with sex and everything that comes along with it…but I’m not sure about one thing…I have symptoms of pregnancy, but they don’t "fit to a T" sort of speek. I am dizzy of and on, I feel sick off and on, I smoke but I feel sick from the smell and/or taste off and on. My breasts feel only somewhat tender though, I’m not throwing up (just feeling nauseated), and I am not constipated. I am only 2 days late…but I would like some more help with these facts before I buy a test. 🙁
