You should probable ask your doctor. Ive never heard of that before. Its probably nothing serious but id still call the doc to make sure
They are like pimples I get then as well. Even when I want preg. But being pregnant also makes you break out so that could be why they just showed up. I would ask your doctor though just to be safe!
