No real symptoms

According to my apps, I should be 4weeks tomorrow. I got my first bfp at 10dpo and the lines haven’t been getting that dark so that’s worrying me. Plus, I only really have sore breasts as of right now with occasional mild cramping.

This is my first pregnancy & not many people know so I feel totally alone! I’m so worried that because the lines aren’t dark and I don’t feel any true symptoms that something isn’t right 😩
