Yes I have one too. It's probably just a swollen lymph node or a cyst. I wouldn't worry unless it gets bigger.
Hi. Well, here is the thing, generally a swollen lymph node would come about when you are ill and it happens as white blood cells accumulate to fight off your sickness. If you have one at any other time, it is definitely something doctors want to know about. If it is a cyst, it is often a bit bigger and can be fluid filled. Mine was aspirated and it was infected. I was seen the day I called about it as it was considered a lump in my breast and doctors do tend to act quickly about that. Sooooo, if you weren't pregnant, I'd say call your doctor!!
However, when I was pregnant, I had little things like that. I had a lump that was actually in a milk duct (even though it freaked me out to find any type of lump) and it went away after a week. So, pregnancy can contribute to these kinds of things.
I would mention it in your next doctors appointment for sure if it has not gone away. good luck
