... 21st I spotted that day, the next day it was on and the next three days I have been spotting. How long will my period be on? Or am I'm pregnant? Me and my husband been trying to have a baby for over a year now and I am 34 years old. I had a miscarriage last year the doctor thought it was an etopic pregnancy but it wasn't it was a normal pregnancy and tubes have been tied for 11 years now.
