Early symptom checking

Did anyone else notice symptoms waaayy before their period was due?

Last pregnancy I noticed my CM increased and my nipples were incredibly sensitive. I noticed that about a full week before I got a BFP. We’ve been trying for over a year and that BFP turned into a loss with twins. So I can’t tell if I’m wishful thinking or if I’m experiencing early symptoms this cycle.

I’m 4dpo and my period isn’t due for 10 days. So I feel like it’s too early to spot symptoms but the exact same symptoms are happening this month. Not to mention I’m extremely emotional, I want to eat everything and I just have that “pregnant feeling”. Has anyone else experienced very early symptoms like this?
