Sharp pain 4 DPO

Co

I'm only 4 DPO and I have a sharp pain just to the left of center at the top of my pubic hair line. Embarrassing but I don't exactly know where my tubes or uterus or anything are other than "down there somewhere." Of course my mind jumps to the worst conclusion that the egg decided to implant in the tubes. Is this a common ovulation symptom or could something be up?
