FRER indent?

Long story short I am on the birth control shot and have always gotten them on time but my boobs have been sore for the past week and a half and i’ve felt a little sick. Don’t have a period so idk when a test would be accurate. But I haven’t had sex in 3 weeks. Took a test last night (1st pic) and with FMU this morning (2nd pic). I’m not sure if these are indents but wouldn’t it be very positive if i had sex 3 weeks ago? These all came in the same box btw.
