@promise1 3 years of infertility and loss for me, and now 27 weeks with my IVF baby. I also took such a long time to feel any kind of joy about the pregnancy because I knew how easily it could be snatched away at a moment's notice. Thankfully, everything seems to be going well now, and at around 20 weeks I started to relax a bit as I started feeling little kicks. I also put off buying anything up until that point (didnt want to jinx myself) and even now I'm just buying little by little.
I know you're (rightly) worried about the hematoma, but focus on the positives - it's being monitored, you and your Dr know what you're up against, and everything possible is being done to help. From here, take the small wins where you can, and celebrate them by buying something you or baby will need. I started to buy something each time we had a good scan, passed the glucose test, felt good kicks etc. It's less overwhelming than having to buy everything at the same time and you still feel like you are slowly getting ready. Same thing with your home space - Maybe clear a drawer or a cupboard that will be designated for baby things. I find it relieving to know that at least progress is being made.
Also, if you have parents, siblings and close friends who know about your journey, you could ask them to help you with getting things together. Put them in charge of your registry if you have one, or ask them to store things for you if you're not quite ready to see the items in your house yet (especially since you're moving). People who love you won't mind and will understand if you're struggling. I hope you have a support network like that around you.
I'm sorry you've been feeling this way, experiencing infertility and loss really do steal the joy of finally being pregnant. But keep going, and don't feel pressure to have everything ready, do what you can when you can.
