Uh-Oh

So before I jump in I wanna say this happened to my mom last year with no signs at all. She was 11 weeks pregnant with consistent heavy periods and negative tests and she ended up having a miscarriage. And had no clue she was pregnant until she lost the baby

So I have this sensation of something moving in my upper/mid abdomen. I have had consistent periods (though they’ve been lighter) and negative pregnancy tests every few weeks ( I constantly need Chest X-rays or CT scans). Am I worried for nothing?
