My last period was early in Nov. and its now Jan. 13th. And I've been spotting very light pink when I go to the bathroom. It latest 2 days now its coming and going lighter than it was during those 2 days. I took a home pregnancy test 2 weeks ago and it came out negative. Ive had slight cramping but no period still. This is not normal for me. I usually will just start. Me and my b/f don't use any method of birth control. Could I still be pregnant if the test came out negative?
