When should you take plan b when your on BC? Like take them together? Its like 3-4 days after it happen i take my regular birth control everyday.

So Friday night like 8 or 9 I let my SO finish inside during the second round of sex since I've been on BC for a month(lo loesterin fe) I got really nervous bit I take my pill everyday at the same time I think I'm only off like the latest 15-36 minutes. I was on day 2/of my second pack I didn't get plan b asap because when I went to Walmart there wasn't anymore and kinda thought maybe I'll be okay.I usually have a sponge it but I was on the moment

-_+ if I get it now for an extra boost cause it still works 4 days after I heard should I take it at 7 with my other pill?
