Brown discharge after positive tests?

Karen

Just wondering if this is “normal” or others have experienced... i am now 2 days late for my period, and did got a positive test at 10dpo and 13dpo 🥳 However the last 2 days have noticed a few brownish spots on my underwear, and very faintly when wiping. I keep freaking out (have had 2 x miscarriages) but trying to stay positive! 😅
