so my period was 3 to 4 weeks late and last monday i took a test. had confusing results to it. retook that Saturday and both said negative. could i just be early on and not showing on a test or signs of miscarrying? because my levels in the past were very low and weve had 5 prior miscarriages. Any advice will be greatly appreciated!
