I am 48, I have a 5 yr old and 2 yr old. My periods are like clock work. I had my last period on March 10. On April 13, I had 2 days of a very light spotting. Pink first then brownish. Took a home pregnancy test lastnight and negative. When should I test again.

I'd give it a week or call your doctor and get a blood test.
Good Luck!
