Is this my period?

💙💙💗Desiree💗💙💙 • Mommy of 2 boys and 1 girl 👦👦👑👣🎀They are my everything

Yesterday I had light pink and today this but only when I wipe nothing else... im 5 months post partum and been on birth control pill. I had taken a first response test and it was faint but then after I took the strips and they were negative. So I'm wondering if I'm probably gonna get my period???
