Should I take another test? (On implant)

I’ve had the implant well over a year now. I let my SO finish inside for the past few weeks, and it’s made me a little more nervous. I don’t have periods. So I took a blue dye test and it had a very faint line. That was a week ago

Went to doctor next day they said definitely negative.

Took another red dye one 3 days later, definitely negative.

Should I take another one in two days or just chill out? I wouldn’t be worried if i didnt see that very small faint little line. I’m pretty sure it was evap but still

(Was on antibiotics for a few weeks (amoxicillin & macrobid) so just making sure)
