I have very regular periods but last month was just plain odd. It came 5 days late and only lasted 3 days spotting the first a little heavier on the second and spotted on the last day. I am 22 and never had this happen to me before besides when I was pregnant so I was wanting some advice I know there's a possibility since I have unprotected sex but I was wandering when to test any advice would be greatly apreciated

Buy and pregnancy test and put your mind at rest.
