Overthinking or cause for concern 🤔

I’m 5wks+5d and since 7dpo I had so many pregnancy symptoms. My nipples hurt so bad, now it’s so quiet I had to check again to see if I was pregnant 🤦🏾‍♀️ my daughter is 3 and this shouldn’t be new to me. But I don’t remember my symptoms going away this early. This pregnancy going to be different, Alil concerned cause I have this achy pain on my right side that comes and goes and sometimes it hurt more when I’m passing a bowel movement (constipated) i want to blame a cyst and don’t think negatively. Has this happened to anyone? What do you think? Am I over thinking? My appointment is next week 🧐
