10dpo first response negative result

Sophia

Hi Ladies I am 10DPO and due on my period on either Tuesday according to Glow or Wednesday according to another app next week. Did a pregnancy test using first response and got a BFN :( is there a chance I can still be pregnant? I have all the usual PMS symptoms and just don't know what to think. I feel like crying to be honest as first response are supposed to be super sensitive and it says 95% accurate if testing 4 days early in the pamphlet :( what do you ladies think? anyone going through something similar or the same position as me?
