Implantation bleed or ovulation

I had a miscarriage in November at 6wk 3days pregnant. Everything returned to normal quickly and I had my period back exactly 4 wks after. My husband and I started trying this month. I am now 8 dpo and since yesterday I’ve had pink spotting, cramps and later brown discharge. Is this a sign of pregnancy (implantation) or perhaps late ovulation? The most confusing thing is that I had this exact same thing when I fell pregnant before, but it was later in my cycle (just before my period). Period isn’t due for 10 days. Advice please!! Can’t stop thinking about it.
