Try not to stress too much! I didn't end up going to any classes (I was in denial about my pregnancy and didn't actually see a doctor until almost 7 months) and managed a drug-free birth with no tears, cuts or need for stitches. If you can't afford it then I would suggest reading a bunch of stuff -- that is all I did. The most important thing I found out was that when it starts to sting, don't push and wait for yourself to stretch. I feel that is how I avoided tearing!! Just trust yourself and your body, it was made to do this. If you ever want to talk then just PM me -- I'm also 21 and in Brissy!!

Take care xo
