So I am on day 8 after Ovitrelle injection(hcg) which i made 9 days ago and I read that usually it takes about 10 days to get out of the system.. did anyone test on day 8?

I see a very faint line and i guess if its negative it will disappear and if it’s positive it should get darker in the next 48 hours, any thoughts?

I am on day 22 of my cycle but I would need your feedback on this one..

Update 1

I got another test today, 10 days from the Ovitrelle shot and I still see a very verryyy faint line, the blue color is from my urinary infection treatment but overall you can see a faint line. Must still be the HCG shot also these are normal 20 ui pregnancy tests, not sensitive or anything..
