Implantation?

Rainy💋

Hi everyone good evening! I’m 4-6 DPO and started spotting light pink on Wednesday afternoon up until today in the am. My period isn’t due for a while. I had a CP in August we tried again last month and no luck but we got 3 days o blinkey smiley face then a peak. Same thing happened this month. Thoughts? Thanks in advance!💖
