So I'm confused. I've been trying for months now and I have had regular periods only. Never late or early..... Few days ago I get this sticky but light pink discharge for two days and I got excited thinking I'm pregnant but today in the afternoon I got little bit more blood (brown on pad ) and so I have pad on and now few hours later it's looking like period....light but red brown ish ?  But here is my question because if this is period it's 7 days early!! And my period always always comes in the morning like as soon as I get up but this came in the afternoon. What could it be????
