Question

Is a cryptic pregnancy possible if there have been negative urine, blood , and pelvic exams in addition to regular periods? My drs have said I’m fine but I’ve started getting weird feelings in my stomach but i haven’t had sex in almost half a year I’m super scared cause I’m a college student and i know if somehow i am i can’t keep it my family couldn’t know and i didn’t even fully have sex I’m trying not to panic. I went to the hospital and had to get an X-ray earlier this week and i got a neg test before it happened so I’m trying to trust that I’m fine but I’m scared it’s almost like a flutter/twitch feeling in the mid left part of my stomach and it’s constant like I’ll feel like minutes at a time. Currently on my period rn
