Implantation or spotting for AF

Tiffany

This is going to really be confusing this month because the last two months I have spotted before my period like 2 to 5 days before and got bfn and then my period comes but very light not like my usual heavy periods for the past 2 months. so this month of ttc I feel like I wont know for sure if its implantation bleeding or AF spotting. does anyone else have this issue. I always get some type of cramps in the week week an a half leading up to af as well. so I'm double confused every month hoping it's a bfp but it's always bfn 😭
