Pink discharge, havent had period since first born

Hi! So today this happen i went to the bathroom n had pink discharge when i wiped. I havent had period since my son was born, hes gling to be 1 on the 17th of this month i do still breastfeed which i know can cause your period to not come, i havent had any symptoms of cramps or discomfort this kinda came out of no where lol but me n my bf have had unprotected sex so i know chances of being pregnant are high, just wanted to know how many have had pink discharge before taking a test?

TIA💕
