sooo I had some breakthrough bleeding before I started my sugar pills that was light brown bleeding and it’s carried over into my withdrawal bleed week, it’s mostly brown but some red blood is present as well. also, it’s never enough to actually go onto a pad, just there when I wipe. is this normal? should I be worried about pregnancy? I take my pills perfectly btw and i’m pretty sure I had breakthrough bleeding bc I skipped my period a bit ago
