Cah, apologies for not responding sooner, where do the hours in the weekend go?
Sorry to read that you're still not feeling comfortable - digestive problems literally are a 'pain in the arse'! Throwing up and pain doesn't sound right. I would go back to your GP or contact your hospital to tell them what's going on. They might want to do another scan to check that nothing has been left behind and take blood to check that there isn't an infection. Please do call them in the morning.
Eight days seems to be a long time without defecating properly, particularly if you are making an effort to eat fruit and vegetables. You must be feeling ghastly. Have you thrown up again since eating the prunes? Forgot to ask you whether you are doing any gentle exercise, for example, walking around, up the stairs, vacuuming etc, anything that gets your metabolism moving more, even slightly?
I really do sympathise with you regarding this. For a month after I mc'd I would feel quite anxious when I needed to 'go'. It was fear of a piece of placenta/clot falling out of me - it didn't happen again so it was unfounded and gradually the fear disappated. Do you think that you may be worried about going? Some people are more susceptible to small changes in their daily routine than others, for example, if I go away somewhere for the weekend, sometimes it doesn't happen, at all! Don't know if it is a change or environment, diet or what!
This is turning into a long response (!) but a couple more tips I read about were to drink lots of water throughout the day (if you are able to stomach it) and to encourage the movement along the gut - pull your abdomen in for a few seconds and then out again, do this in a fews sets of 10 repetitions. Sounds odd but it did help. Caffeine also helps to trigger it in the mornings, I find!
Hope that you get on better this week, you might find that once you've spoken to medical professionals, you feel more reassured and things start improving. I would be interested to know if it improves for you.
