Is this normal? Kind of panicking!

I’m pregnant! Yay! However, I found out 8 dpo, so very early. It’s been three days since and today I started noticing brown/ translucent brown discharge and little brown flakes when I pee. I’ve had cramps off and on since finding out but nothing major. Is this normal or should I keep worrying?
