So I'm new to this whole TTC thing. I had the implanon for 3 years and had it taken out the beginning of November. I've had regular period since taking it out. Fast forward to this week. AF was due on Friday. Saturday afternoon I noticed a little spotting when I wiped but it was just once and have nothing since then. I had a few cramps that afternoon/evening and then was fine. Does this seem normal?
