How long after implantation bleeding can i take a pregnancy test?

How long to NIPT test results take? Anyone know? I get to find out the gender and I can’t wait !!! 🙏😩🎉❤️

How long after possible implantation bleeding can you take a test and it will show clear results ? I had pinkish/brown spotting & discharge only when i wiped, 3 days before my period was supposed to start and it lasted for 3 days then stopped. I had no cramping during the spotting and still no signs of my period coming. I tested this morning, but this spotting and discharge just stopped yesterday and i had a negative test but i was told it can take up to a week after implantation spotting to get a clear result on pregnancy test. is that true ?
