Cervix??...confused

Jessica • Mother of 4, wife of a solider and i couldn`t be any happier.
So glow is saying my period is due today. Didn't show, going by glow I'm 13dpo, took a test this morning, negative. But my cervix is high and soft and I've had lots of ewcm/creamy at times too in the last couple days. BUT if I go by a different dpo tracker I will only be 7dpo. I've entered all the info from glow too. I'm not sure what to think. I wish I could test every morning for the rest of this month but tests are spendy. But I'm confused and don't know what to do....ladies???
