15dpiui after RPL- need opinions

Ok. So long story short I took a test 7-9dpiui, 8-10dpt and my trigger was still in my system so I stopped testing. I then took a test in the afternoon on 13dpiui (top test) on 14 dpIUI (middle test) I had a beta, and it was only 37 🥺, so I took another test this morning hoping it would be obviously darker or lighter and it’s faintly lighter. Do you think this is a chemical pregnancy? Or do you think the trigger could’ve made my 13dpiui test falsely darker? Has anyone ever had this variability in their first response and it be ok?
