Discharge Question 😬

Hey ladies! So my husband and I are on month #4 of ttc and my period was supposed to come yesterday and it didn't and still hasn't today, and last month my period started the exact day Glow said it would. I know it's only 2 days late but I'm excited😂 I've been exhausted all week and have had cramps and my boobs are killing me, and the last 2 days I've had clear watery discharge and no period. I'm very hopeful but trying not to get too carried away! Has anyone else had clear watery discharge when you should've started your period?
