OP this post is a few hours old now if still nothing, you could try a single dose of milk of magnesia to get things going but continue a high fiber diet the next few days to get everything back on track.

This reminds me. Apparently, in a pinch, you can also dissolve a few teaspoons of epsom salt (magnesium sulfate) in water and drink that. Would have never guessed that stuff is even safe to consume if I hadn't read "saline laxative for relief of occasional constipation" on the front of the bag I just bought.
