Last Tuesday? It’s now Sunday…. Plan b is effective for up to 48 hours after unprotected sex, the sooner you take it better. Ella one (another type of emergency contraceptive pill) is effective for up to 72 hours after unprotected sex, again the sooner you take it the better. No point taking an emergency contraceptive pill now it’s not going to do anything. All you can do is take a pregnancy test 3 weeks after sex.
What do you mean by not on the pill? Do you mean you were on your break week/placebo pill week? As you’re now taking pills again?
