2 month ago me and my partner are had sex it was fully protected but suddenly the protection went inside her private organ which might have my sperm so we took it out and stopped there and next moment she had an ipill within an hour and she had her periods next month may be a week or 4,5 days early than usual. Now from two days she is feeling unwell because here is to cold and she is haveing fever and feeling like vomit and headache. Is it possible that she will pregnant? Or its happening because of fever
