What do we think

I’m literally only 6/7dpo and my lh is dark again and my wondfo tests have very faint line and have all day? My bbt chart looks like it’s confirmed ovulation for the correct day too can anyone else see the line? I had a miscarriage at the end of last month but my hcg levels were tracked down to 0 so I’m not sure what’s happening! I didn’t think it was possible to get a positive this early?
