Chemical? Still hopeful

For the last three days I tested everyday and Got a “PREGNANT” I started testing the day of my missed period …Im 4wks and 3 days today . I woke up to light bleeding bright red so i decided to test again using the last test i have left and today I got a NOT PREGNANT.. im going in tomorrow for blood work..

Did anyone experience something similar and still ended up still being pregnant and have healthy birth?

IM SAD,HEARTBROKEN BUT STILL HOPEFUL 😭😭😭😭😭😭🤧🤧🤧🤧
