I had a miscarriage at 10 weeks on 7/21/19 passed everything and stopped bleeding 4 days later. I was told once bleeding stopped I could resume normal activities. My hcg was 4 on 8/9/19. I was told to count that as a period. And counting that as a period would put my ovulation date as 8/4/19. Today 8/11/19 I had clear discharge with light pink blood when I wiped. My period isn't due for another 7 days if it will be on time since the miscarriage. I assumed that it was the start of my period but nothing in the toilet, nothing in my panty liner. (I put one on assuming it'd start and nothing.) Could it be implantation spotting? Should I not get my Hope's up? When should I test?
