Should I take a test?

Breanna
I recently got engaged and I've been so busy lately I forgot when my period was suppose to start. When I went to come look it says I'm 9 days late and 38 days into my cycle I've never been this late and not known about it. I've been throwing up in the mornings. Can someone help plz? Now my nipples hurt really bad I'm on day ten still no period. Didn't get sick this morning.
