I am currently 19dpo .. Period is late by 5days today all my tests are negative .. I’ve tried like 3 different brands .. I’m never this late I have no signs of AF showing up .. I just feel really tired and just yucky most days headaches and feeling cold a lot .. today I decided to take an ovulation test and it came out as high just like how it would before my peak .. not sure what this means or if I should wait a few days to re test or call the dr .. has this happened to anyone and then got a BFP later on ?
