I know this is dumb but I'm paranoid so plz be kind. Over the past week I've found out I have a heart arrhythmia and I got heatstroke, last Tuesday I got my period but it was not as heavy (it still was red blood though) as it usually was and had a lot of clots, it lasted about 7 days as well. I'm thinking it's because I used a tampon or maybe because of what happened to me. My doctor made me do one of their pregnancy tests and it came back negative, do you think I have anything to be worried about or am I pregnant? Or is just me being silly?
