Midwifery is highly competitive, not to put you off at all but to manage expectations, your application needs to be excellent. Many universities also stipulate that you need to have studied in the past few years, so you may need to do an access course, it's worth checking the info pages of the unis you are interested in applying to. In general though the process is:
Apply via UCAS, I believe they open in Oct still for applications, you need 2 references, a personal statement and to choose your university choices in order of preference.
You hear back from universities regarding whether you have been successful at securing an interview or not, this can be months after sending off your UCAS application.
If you had an interview you will be informed of the outcome, if successful it will either be conditional (if you are awaiting exam results), or unconditional (if you have everything you need, it means you deffo have a place).
When your place has been confirmed you apply for student finance, I believe the bursary is applied for separately, but either way you don't need to really worry yet.
I'd start looking at access courses, some you take a loan out for and don't have to pay back if you go onto further education, others you pay for. You can do them online or at college if a local one offers it, but you'd have to be quick to even have a chance at a place for this year.
Also start looking at how to enhance your application, it's hard to get ward experience at the moment, but check out free courses online, volunteer with breastfeeding support and local groups etc.
