Phantom letdown?!

Evy
Ok, so any mommas that have breastfed...are phantom letdowns or tingly breasts a pregnancy sign? I'm 8 dpo and several times today have had the feeling that I can only remember as feeling like a letdown. This would be month 4 of trying and definitely the first time I have felt this leading up to af. Anyone else experience this and ends up in bfp?
