Cd 60

Tested negative yesterday cd59. Still no sign of af. Had the smallest amount of brown spotting and cramping over the weekend and only was in the mornings when I wiped then disappeared. Haven’t had any since. Spoke with my dr yesterday and she said 4 months with no period and negative pregnancy test to come in for blood work. Going to test tomorrow morning🤷🏼‍♀️. Should I test every few days? I went all of January without a period and now February is almost done. My last period began Dec. 21.
