6 weeks 4 days

So I’m 6 weeks and 4 days and my symptom that I had, (sore boobs) has seemed to have subsided, maybe a odd twinge here and there but not like it was. I know symptoms can come and go but I’m just worried something is wrong!? I’ve taken about 6 tests in total and the line has got darker each time. Am I just panicking and everything is fine or has anyone else experienced this? I’ve posted the two recent tests below. One was taken on Wednesday and the other was taken on Friday.
