What to expect?

I’m just a few months into the whole TTC, and am struggling to know what to expect… And Im terrified of getting my hopes up…

my period was due yesterday, or the day before, and the last two days all I’ve had is some thicker white vaginal discharge, and a few episodes with light cramping at my lower back. I don’t know if it’s too early for pregnancy symptoms, and I’m too scared to test…. Anyone with any experience, or who knows what I should expect? 💕
