3 days late, short luteal phase, pregnant?

[JayDanny]

The morning of the day my period was supposed to start when I went to the bathroom and I wiped I had a little bit of pink blood mixed with clear mucus. So I thought, "Ok, I'm starting my period today." I prepared for it but I haven't seen a spotof blood since and I've had no cramping or irritability that usually come with my periods. Is this wishful thinking or could I actually be pregnant?
I'm not sure when I ovulated this month but it may have been the 15th and my luteal phase is 9 days.
ps. I was 13 days past the first day of my missed period before I got a positive home pregnancy test, with my daughter.

Have you tested?

As above ^^^ it might either be the start of your period or implantation bleeding. Good luck x
