Hi there, I think that birth plans are a little over rated because they give you the illusion that you have control over the whole situation, which isn't necessarily true, as in all aspects of nature (or I'd have ordered better weather for my wedding day!!)
However swap the word 'plan' for 'preference' you can keep the content wholly positive, focus on what is important to you and OH (skin to skin, cord cutting and whatever you feel is important) and give yourselves room to make choices during the birth.This mind frame is especially good if you have any known difficulties with your health along the pregnancy and overall its the small and simple things that are often the most meaningful to you both.
When making choices you need to weigh up the benefits and risks - because all actions have both, ask about alternatives courses of action, check your making an informed choice (so read around and understand the possible medical interventions and the policy of the establishment) and of course the need - whatever happens it has to be because its in the interests of both your well-being and not because it's nearly tea time!
Personally my plan is very simple, I want the opportunity for my body to do what it knows it needs to do, I want skin to skin asap and I want my husband to be with me (but not the business end!). I was considering delayed cord clamping and natural 3rd stage however as I'm on anti-coagulants I'm recommended to have a managed 3rd stage, and given that the I was quite tired the last time I had a baby and I don't want to bleed too much, especially if I tear again, I'm ok with that.
I wish you all the best as I know you've not had the easiest time so far and I hope this helps x
