My friend (Female) had unprotected sex on 11th Jan , where her partner ejaculated outside. She took i pill within 7 hrs. And from 19th Jan she started bleeding dense blood /clots etc almost like a period. And still bleeding. Concern- for how many days this bleeding will occur . Since this is way more than just light spotting . Last period date was 2nd Jan. Before that was 5th December. (Had protected penetration on 1st Jan so maybe got period earlier because of that. ) When will she get her real period. In February? And how much delay/earlier the period will come? . Will this bleeding lead to a lighter period?
