30 Weeks Pregnant is this Normal???

Chelssie

For the last two days I've had a light bleeding (only when I wipe) after taking a bowel movement, twice. I thought the blood was from this as I'll check hours later to see if there's anymore blood, from anywhere down there, but there isn't. So, I chalked it up to pregnancy bowel movement issues. Anyway, today I noticed spotting, old brown blood, in small amounts only after I wiped after peeing.

Does anyone know what this is and why its happening?
