Hi manda,
I am sorry i can't help you with the lower kicks, but hopefully someone else can. If you are really to uncomfortable and it is concerning you alot and you can't wait for your appointment see if you can ring them and talk to them or maybe change your appoint. They may be able to give you some tips on how to ease the pain a little or maybe there are some different positions you can get in to see if you can help to move the little one around to a more comforable position for you.

Best of luck
Kas
