I'm sorry you are going through this OP. Have you given birth before? I made the same decision with my 1st pregnancy which had patau syndrome. Sorry if this is long and I do hope you don't need to go down this path, but these are things I wish I'd known beforehand. Sorry if TMI also.
I was only 12 weeks, and abroad, so possibly the reason things were done slightly differently. I was admitted to the hospital, and had 4 tablets inserted vaginally. No oral tablet beforehand, nor any 2 day wait. It took maybe 6hrs before contractions started and I was kept overnight for monitoring and to speak to the genetic consultant etc.
Before they put the vaginal tablets it, go to the loo and make sure you have a massive pad on. If possible, lie in bed for as long as you can and let the tablets dissolve. When you do use the toilet, you might see a white paste come out, part or even a whole tablet come out. It will still work. I took night time maternity pads with me, but often the hospital will have something bigger- like a massive adult incontinence pad. They might recommend walking about and moving after a certain time. This will help the cervix open.
A side effect of the meds can be diarrhoea, nausea, vomiting and a high fever. This isn't an allergic reaction, just very common side effects. My face burnt up and I looked like a beetroot. Ask for paracetamol or stronger pain relief to help with the fever and any pain. The symptoms do resolve though.
This was my 1st pregnancy and being only 12 weeks, for some reason, it never occurred to me that waters would break! I wish I'd been wearing a massive pad! Take at least a few large, loose, comfy full brief underpants and an extra pair of PJ's.
My scans had shown many birth defects. A large hernia and a cleft face- not just a cleft lip, being just 2. I was also only 12weeks and had decided beforehand not to look. Years on, I'm still content with my decision on this. The staff 'might' offer to do hand/foot prints or keep things in a memory box for you.
The following day, I was feeling physically ok. No pelvic pain, no fever etc and walking about. Just felt a bit fragile. Another thing I wasn't expecting, was being asked what plans I had for the foetus. Again- I'd honestly never thought about it till I was asked. The baby had histology/autopsy done, but they wanted to know our wishes after that. My choices were to pay and organise a private funeral or have the baby given back to me to bury myself at home. A 3rd option was that he'd go with other early pregnancy losses to the local cemetery to be cremated after a chapel ceremony, and the ashes put into their 'Garden of angels.'
Once again, I really hope you don't need to go down this path, but more than happy to answer any questions you have. You might find ARC can be helpful too. Just remember that you did nothing wrong to cause this, and you aren't alone going through this. ❤
