Me and my partner had intercourse in october and that with protection and that was not broken and she had her periods 1 day late in october and in november she got her periods 4 days early but she had vomitting also some days back and once she felt nausea also...we tested in october ending and that came to be negative..we are worried that can she be pregnant if she both her periods in both the months but in this month they were 4 days early...
