5dpo symptoms

Indigestion, fatigue WITH insomnia, nausea, backache, cramping, creamy sticky CM falling into my undies. never been preggo before so not sure how it feels! Implantation hasn't even happened yet so I'm wondering if these symptoms are pregnancy related or not.. probably not yet anyway. Maybe they're all psychological LOL. This is my first month actually tracking my OPKs and cervix positioning, CM as well. Baby dust to all!
