Light Brown/Red discharge

Hello :-)

I’m currently 5+3 weeks into my second pregnancy (my first ended as MA in week 5) .. Yesterday after yoga I spotted a bit of Brown/Red blood but it stopped immediately and I thought it might have been due to my excercise .. This afternoon I’m again seeing light brown spotting .. Just a bit , but still .. Getting really concerned this is just another beginning of an abortion :-( .. Anyone else who has tried that?
