If I were you I would slow down. You said you are at 10g right now and have been for only 6 days. Stay there for at least 3 more weeks. It is recommended to wait 4 to 6 weeks at smaller sizes. That is the best advice anyone can give you for not messing up your ears.
Secondly, see if you can find some stainless steel plugs instead of acrylics. Others recommend glass. I personally have not used it, but many people on here recommend it and have had VERY good results. This will help with healing immensely. You DO NOT want to put acrylic in a fresh stretch. Acrylic is a porous material that is not really conducive to good healing.
It also sounds like you are wearing your tapers instead of putting plugs in right after. This is also another no no. Keeping tapers in can cause uneven stretching, and they can get bumped around causing irritation to the fistula (inside of the piercing). Check out this sticky on the forum too

If you are having trouble finding stainless steel plugs check out
http://www.bodyartforms.com. I recently ordered from here and got an 8g stretching kit with steel plugs for only $5. Even with shipping it was still cheaper than going to any store in the local mall or piercing shop.
I hope that this helps. I have just started stretching over the past few months and have gotten some really good information from this site. Read as much as you can. There are some really knowledgeable people on this site who are more than willing to help so we can all have some sexy healthy stretched ears!
Good luck stretching!
