Chemical pregnancy maybe...

Has anyone had a chemical pregnancy without cramping (I just started bleeding I would be 4 weeks pregnant no cramping) I’m waiting on lab results I’m suppose to get this afternoon but this is crushing me having to go through this when I thought I got my BFP on Halloween to now all of a sudden losing what I thought I had completely heartbroken 😞 I’m just thankful I didn’t tell anyone except my fiancé and we both broken by this
