Missed period with implant!

I got the implant 1st august this year. I had unprotected sex about a week after(when it starts working) but I also had unprotected sex before it started working😅but my partner pulled out. So I haven't had any spotting and my period came on time but it lasted 10 days and now nothing since. I've completely missed it. My next period should be due soon but idk if it will. Is still normal? Periods can stop with the implant but I thought they had have been light, shorter and irregular then stop. 😕will pregnancy tests be accurate if I do take one?
