Was the transit study you did called a smart pill test?
I had the other transit test where you swallow the 24 rings in a capsule and they xray you every day for 5 days. But they never told me to stop the laxatives beforehand or during 😭 and on day 5 of the xray I only had 5 markers left so they said it was normal transit. I struggle with my bowels everyday. I take Miralax nightly and Motegrity every morning.
