Just went pee and looked in toilet and they was bloody mucus in there. I'm 34 weeks ????

It was a size of a pencil eraser

How much blood? I'd call your doctor it's to soon for a bloody show your still preterm...

even if it was a little bit??

That's your mucus plug. If it was bloody you need to let your doctor know because that's your bloody show and you're still preterm
