I think the blue dye always gives evap lines so I'm not sure about the test I took. However I have been non stop cramping the past two days. Shooting cramps. 😢 can't tell if af is coming or not I haven't had a cycle for November and glow said the 29th was my due af. Well nothing happened yet. So it's the 1st if I don't see AF tonight then I will test in the morning or should I wait....?
