So I’ve been getting shadows on one steps this week, I think I’m about 12dpo. Today I started light bleeding (not enough to fill a pad but a few specks and there when I wipe) and cramps mainly in my lower back. This evening Iv taken another one step which shown a faint positive within one minute! What are your thoughts, is this likely a chemical and is there a definite faint line or am I going crazy?!
