5dpo - Dull Aches and Cramping

Ellice

Hi Yall i'm currently 5dpo according to glow and I've been having dull aches and cramping from about 3dpo..could this be a sign? I looked in my underwear when I went to use the bathroom and noticed a slight pink tinge in my discharge which has increased a bit...any thoughts? Thanks ❤🌹🌼
