Jillian
So I am 3 days late according to glow and my cycle ranges from 31-35 days... so it's safe to say that now it's cycle day 35 and still no af. So the only symptom I'm feeling is being totally exhausted and my boobs are somewhat sore.
The only thing that stands out to me is that about 7 days ago I felt this Excruciating cramping that lasted for about 20 minutes. Then went away. Then about a day or
2 later I experienced 1 spot of light brown/pink spotting. 
So I think it's time to test, what do you all think??
