My husband and I had an accident on June 23 so I had taken plan b one step on the 26th. And another on June 29th (condoms don't seem to work in our favor) and because I had already taken plan b this cycle I didn't want to take another one. I started spotting brown on July 6th and I could only see it when I would wipe and this lasted until July 10th when it got a little heavier and started turning pink. I thought it was my period so i had used a tampon through the night and this morning it was maybe a quarter of the way used. I usually have a 28 day cycle and my last one started June 16th and I am not due for my next until July 14th. Is this normal?
