Question about plan b!

B

So In January I had my period for 3 weeks or so because I took plan B. Jan 4th - 24th.

After those dates been I have been sexually active. My question is , would Plan B delay my period still? It’s Feb 7th and still no period.

Wondering if the pill would cause my cycle to mess up. ( didn’t take it again , just that one time in January )

Sorry if this is all over the place , thanks!
