Should I Be Concerned?

This is my 3rd pregnancy, and based on my last cycle, I literally just hit 4 weeks today, but I found out last Saturday. Last week I was having these nagging headaches, but after I got my BFP, those subsided. Since then, the most I will feel is when I eat sometimes it feels like my food is sitting in my throat, I pee more, have small aches and have been tired more often. But compared to my previous pregnancies, I haven’t had much discharge increase, boobs hurting or anything else I’ve experienced in the past.. I don’t know if I’m overreacting, or overthinking, but just wanted some thoughts and opinions.
