Hey yall! So this morning i took a cheap hpt from dallar store and it was neg. I am 12dpo.. 2 days until expected af comes (according to glow.. i say this bc i can have abnormal cycles) and when i went to the bathroom i had some light brown discharge on the toilet paper light in amount. Also i have been having some mild cramping. What do yall think?
