Can I test?

So my last period ended on July 23rd, and I ovulated on or around August 6th, I started noticing some slight blood only when I wipe( light pink or brown) on August 10th but it hasn’t stopped, not ever heavy and my period isn’t due for another 5 days, implantation bleeding? And if it is implantation bleeding when can I take a pregnancy test? Do I have to wait for the bleeding to stop or because it’s been going for so long can i take one now? Me and my husband have been TTC for a year so it’s super nerve wracking!
