Loss of breast soreness- bad sign right??

I'm on CD19 today (9 days past IUI). I had breast soreness for about three days CD5'ish to yesterday, but today really nothing. I'm assuming this is not good. My BBT has gone down a little (was at between 98.3 and 98.4---yesterday 98.1 and today 98.2). The thing that's totall throwing me off is that I was prepared that this cycle was a bust with having to put our cat to sleep three days aftet the IUI (and having some cramping then), but then my acupuncturist on Friday switched my herbs (which she's never done in the four months I've been going there) and started talking to me about how when your pregnant it's harder to feel hungry etc., so milder herbs are easier to deal with. I'm lying there saying in my head, "But I'm not pregnant." I didn't have the nerve to ask her if she thinks I am. I wasn't prepared for her to say, "NO." --but with the loss of breast soreness, I'm guessing the likelihood is decreasing???
