Super bummbed out 😭

My periods due in the next 4-5 days. I take a pregnancy test bc we havent been using protection and i see what i think is another line, i took one yesterday and the day before nothing popped up, but today this popped up at 3mm. I go to wipe after POS i see light pink blood on tissue none on underwear 😭😭😭😭 whyyyyyyyyy 😭😭😭😭😭😭

Update: I went back to the br and i wiped and theres nothing, no blood or anything. 🥺🥺🥺 idk whats going on
