At the beginning of this month september, I came on my cycle which was mostly very light and spotting instead of a regular flowing period. It last from the 1st all the way up to the 3rd. on September 26 I started spotting again and it's been on and off from that day all the way up to now which is the 28th today. I been using tampons but when I take it out to change out it's only spots which look like dry blood on it. I took a test yesterday but it came up negative.... Last month my period came on the first and then like I said it came on the first again this month but now it came back on the 26 and it's been on and off spotting up until now which is the 28 What could be wrong with me? Could it be something else beside pregnancy because my test came back negative???
