Could it be

I'm confused as to what could be going on with my body. My so and I have been TTC baby number 2 for a couple of months and nothing yet. Well I was supposed to start AF last Wednesday and nothing. Well I think I may have ovulated late and might be experiencing implantation. The other day I felt a very sharp pain near my right ovary it lasted about 1 minute and haven't felt anything since then later that night I wiped and there was a small streak of pink blood so I thought maybe AF was coming but It never has. So ladies I need your insight could it be implantation or something else. Im keeping my fingers crossed. Thank you for any input
