Struggling to get to 4G

Hi ! im really struggling to get to 4g. I had my 6's in for a little less than 7 months when i decided to get my half sizes. I've had these in for about 3-4 months, maybe longer ? They have stretched a tad bit. And actually to be clear, my left lobe i can get my 4's in but my right ear is just not wanting to stretch. I do sleep on my right side so i'm thinking that has something to do with it. Anyways, my question is would it be worth it to get some Weights to help move it along ? Should i just keep waiting ? i'm making sure to clean them regularly as well as oiling them regularly they're just being very very stubborn and not sure what the next step should be if anything at all. Any advice is greatly appreciated ! Thank you all in advance !
