please help! im freakin out

ashley

any advice would help!! so i am 5 days late. last night i went to take a shower and noticed a heavy string of white cm on my panties, which is strange bc i expected it to be my AF.

today still no sign of AF but i think i had implantation bleeding bc it's not heavy but it is pink bleeding when i woke up. i'm cramping, and my back hasn't stopped hurting for 6 days straight.

every test i take says negative, even today. any advice???
