Stressed 😭

I feel like I’m totally stressing this whole TTC thing. Here lately I’ve felt totally bloated, cramps, mood swings, and nauseous just about everyday. I’ve also noticed here lately that my boobs are sometimes sore. I got 7 flashing smiley faces on my ovulation test, and am unsure when I should start testing. My last period was October 2-6, and my expected period is supposed to start on Oct 30-2. My fertile window according to the app was Oct 11-17, with the 16 being my ovulation day. I’m scared I’m stressing myself out too much about the situation and I know it will happen when it’s supposed to, I just need some calming advice.
