is pain normal AFTER passing a stone

I recently had a 2mm stone for nearly a whole 4 weeks. Just had a ct scan and it said no abnormalities found, so i am assuming that means the stone has passed. i haven’t contacted the dr yet since my checkup apt is scheduled this coming week so i will just wait til then to ask questions. But i got the news about a week ago that the scan was clear, and all day today I have been having that spasm pain. not the total “stone is moving” pain, but enough to make me take pain medicine and be uncomfortable. My question is, is this normal to have pain like that after a stone passes? could another one have formed that fast? also a question for any ladies on here, if you start your monthly a week after passing a stone, does the natural swelling in your body make this kind of pain happen? thanks for any help.
