Glad you enjoyed your holiday! That's funny I tried the sensura Mio concave as it sounded perfect for me but I also leaked. I think it's too hard a base plate. I use a salts convex and luckily it still fits. I'm cutting at 52mm due to the size which I think is caused by bump and hernia.
I've had my stoma for 4 years and the hernia for probably around 2/3 years. I met with my surgeon at around 19 weeks due to partial obstructions and to discuss a repair, he told me that as baby grows there should be less pressure from the hernia rather than more which was a relief to here as I was feeling a lot of pressure and pain. The hernia is definitely still there but apart from an incident following iron tablets I've had no further obstructions (touch wood) and my stoma has not grown any more.
The hernia has caused my bump to be lopsided which does bother me a bit. I look further along from the left than the right :)
@starkid I'll be having an elective c-section on the advice of my gastro consultant, my stoma was placed due to fistulas (Crohn's) and repairs haven't worked so it could cause more damage if I had a vaginal birth. Due to the stoma I'll have a colorectal surgeon in theatre during my section in case my bowel is damaged when they cut. There could be scar tissue so they're covering all bases but it should hopefully all be straightforward.
I've had 6 scans so far but the early ones were due to a previous chromosomal abnormality in my last pregnancy which was spotted at my 12 week scan and confirmed by CVS. This was not related to Crohn's or the medications I take, it was purely just one of those things. From 20 weeks my scans have been to check growth due to Crohn's meds (azathioprine and remsima) I am consultant led and have discussed my medications and birth plan with my gastro consultant who I've seen twice during pregnancy and I'll see him again next month. I am well looked after, my obstetrics consultant has been in touch with the surgeon and gastro team.
Removing my rectum is the next step for me as meds aren't really helping. I was told that this could effect fertility but I don't really know more about that. Maybe your gastroenterologist could refer you to discuss this or he/she may be able to advise. If you're ready to try I would go ahead :)
Sorry, my reply is a bit of an essay!
