Hi Iv Just Been Discharged From Hospital This Evening I

Hi
iv just been discharged from hospital this evening I was admitted yesterday with severe lower right abdominal pains, iv got really sore rebound pain & iv just started my period last night. They carried out a pelvic ultrasound but I'm just thinking I put a tampon in on Sunday n I can't remember takin it out! Surely the sonographer would have noticed if I had one in there somewhere?
