Is this a good sign?

So usually I wouldn’t be 100% sure of when I’m ovulating because I don’t use ovulation strips, just the app. Anyway in December I knew exactly when I ovulated because I felt the cramps like I used to when I was younger. I had sex two days before I ovulated and on the day. Now, it’s 5 dpo and I woke up this morning feeling nauseous and the feeling has gotten more intense throughout the day, my boobs feel heavier than usual but unfortunately I can’t decide if my areoles are darker. Could this be a good sign guys?? Like could I really be having symptoms this early?? Please say yes😭
