Plan B going back on BC Help? Should I retest one more time even if I got a period ?

Hey I had sex June 20 took plan b June 21 he pulled out I got off BC a week prior and had a withdrawal bleed. I took plan B within 11 hours after.

So I tested July 4 negative

Got my period July 7 and I’m on the second day now. I’ve been testing all along and it’s negative.

Do I have to retest again July 11?

The doctor I talked to said July 11 retest would be waste if time.but if I wanted to I could go ahead.

I was planning to go back on BC July 15 and retest that day as well.

My breast tenderness and everything is gone now.

Just have a period !

Help!?
