My cycles are 40 days apart. I used a chart and it said that I should have ovulated last week. My boobs were sore last week and still are but not as sore as last week. Yesterday when I went to the bathroom, when I wiped I had pinkish cm, but now it's gone. My AF is not due until the 31st. I also have been having mild cramping since yesterday, but not very often. I kinda feels like my AF is coming, but when I go to the bathroom, there nothing there. Could I be preggo?
