Are you doing / have you been doing your perenium massage op? If not it's never too late to start. Olive oil will do and is much cheaper than special 'perenium massage oil'.
I had a straightforward labour and delivery with my ds who is now 10 months and personally found being in the birthing pool massively helped ease the pain of the baby actually coming out.
I had a second degree tear which I had no idea I had until I was told.
The stitches were completely fine. They numb the area and I distracted myself throughout the procedure by charging to the lovely student midwife about the perfect cup of tea! Also staring at my fiancé and son was amazing and made me almost forget the stitches were being done!
The recovery was harder than I'd expected but there's preparation you can do to minimise the pain e.g. stocking up on baggy comfy clothes. Lots of good YouTube videos on this.
My 2 top postpartum recovery tips:
Buy a sports cap bottle of lucazade to drink during labour. Save the bottle afterwards, rinse it and keep it by the toilet. Use it to pour luke warm water on your bits as you wee. This really helped me for the first ten days or so!
Have 'stations' dotted around the house with useful things in. I had a box by the sofa with stuff like hair bands, deodorant, snacks etc. Bedside table - snacks and painkillers aplenty! Toilet- empty bottle (see previous tip!), 'intimate area wipes' bought from boots and used instead of loo roll in the early days, thick maternity pads and nappy sacks for used ones.
Good luck, you'll be fine
