Me and my fiancee had sex last month during her periods. Her LMP was on 13th Aug 2019. To be on safe side she did a urine
pregnancy test on 8th Sep 2019 which turned out negative just before 5 days of her upcoming periods . Her next due date is on 13th Aug 2019. Usually she gets her periods 2-3 days earlier than the due date . Today is 11th Sep 2019 but still no periods but she can feel slight pain in her abdomen from 2-3 days back. Was it fine to get a urine pregnancy test 5 days ago before the periods date ,is it reliable . Plz guide
