Help 😭

Last date I had sex was 7th July. Tested on first day of missed period and was negative so assumed not successful this month. Now 5 days late and testing again. This is within time frame but had the dye just run? Also given the timeframe if it was viable, I would’ve thought I would have been darker 😭 - I’ve had 3 miscarriages in 9 months so this isn’t my first rodeo unfortunately but I am spiralling 😭
