Could I be pregnant? Help!

Carly

I'm not sure how many dpo I am. But I keep cramping and my period is like 8 days late. If I calculated correctly. I have severe endometriosis which I know can mess up your cycle and make you nauseous. But I don't think it's ever been this late.

My breasts have been sore for maybe a month but I assumed it was PMS. But still nothing.

I've had some watery tan discharge. (Is that normal?)

I took a test yesterday but it was negative.

Could it be too early to tell?
