On mar 29 th we had sex with protection after 3-4 days she is having some pain in stomach and sometimes vomiting sensation. We used a condom which didnt broke and before cum i stopped so is that a problem. Will she be pregnant. Her last period date was 16 th march . And today is 13 th april still she have 3 days . But this stomach pain and sometimes vomiting sensation leads to a tension and stress . Please help
