Is everything okay ?

So I just found out I am pregnant a week ago. I have not been to the dr yet. At first I had severe pregnancy symptoms even before I got a BFP. My breasts were extremely sore and swollen, very nauseous and had headaches pretty much every day. The last couple of days my breasts don’t seem to hurt anymore and I’m feeling a lot better, just very tired. I am getting nervous and am wondering if it is normal for symptoms to go away this early in pregnancy. I took another test yesterday and my levels are obviously going up because the line is darker than the other ones I have taken but I still feel nervous that my symptoms are changing.
