After Pill

So had Unprotected Sex on the 5th(he came in me) at 3am. barley had got off my period aswell, I took the emergency contraceptive at 4 today 😐.. this will be my second time ever taking it, the side effects are so horrible.. But what do you think the chances are it will work? 🤞I have irregular period aswell.. gunna be 20 this month and this still isn't on track 🤦
