Sharp pain tww

El

So I’m in my TWW I’m around 8-9dpo or so I had a sharp shooting pain on my left side of belly button but a little lower lasted maybe 30secs if that but it was a stop what I was doing sharp pain never had anything like that. Made me almost nervous. So what could it be? Maybe implantation? Af coming? Or something different? I’m on my first round clomid!
