Lower Abdominal Pain at 6dpo

I’m ~6dpo today (positive OPKs Monday-Wednesday with temperature spike on Thursday) and started getting some cramping today. I’m on CD 23 but still 7 days away from AF. It’s gotten a bit worse throughout the day and it hurts any time I laugh or cough. It’s not localized to one side or the other and it feels a bit like a strained muscle although I haven’t done anything to cause that. Could this be implantation cramping?
