So Scared

For two weeks before my positive pregnancy test my breast were tender and sore. For the past two days now it’s gradually went away. It’s worrying me because that was the first thing to happen and leave with my missed miscarriage five years ago. So I’m freaking out. Is there any reason it would be doing this other than the worst possible reason?? I’m 5+2. Any input or opinion would be helpful please- anything?
