Hi so I’ve had multiple faint positives and multiple negatives I am 14 DPO and my period is supposed to come tomorrow my results keep changing I took a test today and it was negative. Should I get a blood test done if I don’t get my period or should I wait longer to test??? What should I do?? I had implantation bleeding that lasted about 4 days. And i know for sure it was not my period because I had already had my period. My symptoms I am having are extreme exhaustion,fatigue, extreme frequent urination, cramping on the right and left side. And mood changes. And extreme lower back pain off and on. This app says my period is 6 days late and flow says my period is tomorrow.
