I’m about three weeks into my pack (this sunday I will take my first sugar pill) and lately I have been experiencing some breakthrough bleeding i notice when I wipe. I am not pregnant because I had my withdrawal bleed last month and it was normal. I don’t experience breakthrough bleeding often. is this normal? I have never missed a pill and I take it on time usually, and when I am late it is only like an hour late. Ps I’ve been on the pill for about a year. thanks guys :)
