Hello, I would be happy to help you with your question.
It sounds like your efforts to improve your constipation
have been too effective. In the setting of excess bowel movements (I am assuming diarrhea
based on what you have said) hydration is critical. I would stop taking prune juice and move away from the liquid supplements to your diet. You can buy medication over-the-counter for diarrhea (often called Immodium), but it might be worth running this by your OB/GYN given the critical gestational age
of 23 weeks. It might be worth evaluation to make sure that your are not in labor.
I hope that this helps. If you have more questions, please click on "ASK ME A QUESTION" link above to directly ask me a question!
