Miscarriage- and trying again.

2 weeks ago I had a miscarriage.  I had only know I was pregnant for a week before.  Friday afternoon I noticed light pink spotting- and had gone between light brown and light pink until this morning.  Since my miscarriage, any sign of blood feels disheartening.  I'm wondering if it would be too early for implantation bleeding?  Or is it more likely bleeding due to ovulation?  Which by the way I do t ever remember having before...
