Discharge with period?

I have googled everything and I can’t find anything about it.

My “period” started yesterday. I have been bleeding, but hardly enough to fill a tampon.

But with the blood, is a ton (and I seriously mean a lot) of thick, clear discharge.

Is this normal? I have been ttc for about a year with nothing.

I have taken a test. It was 4 days before my expected period (5 days ago).

Should I just take another test?

Is this a normal thing that happens sometimes?
