Help! Is this ovulation spotting?!?

Angel • My Husband and I have been married since Jan 15, 2015. We are pregnant with our 3rd and last baby (2nd together). We have a 3 year old daughter a 16 year old daughter from a pervious relationship and he has a 14 year old daughter from a pervious relations

So on CD 19, at 12AM and at 10AM I tested and got positive tests. See pics below. We BD twice on CD19. Then today I wipe and get a bit of pink spotting, see picture below. Is that ovulation spotting? We are planning on BD again today, tonight and the next 2 days. Do you think we have a chance this month?
