I take Gildess Fe 1/20. This morning, instead of taking the last white pill for week 3 (Saturday), I accidentally took the first brown pill in week 4 (Sunday). I've never missed a pill or done that, so what pill should I take tomorrow (Sunday)? After taking the brown pill today, the last white pill is still in my pack, as well as Monday-next Saturday of the brown. Should I take the last white one, and then Monday continue like normal with the brown? Or now go ahead and continue with the brown? I just didn't want to get off track with my packs now.
