Counting Myself Out

Cecilia • Mommy to our rainbow princess Manuela Carolina (born Feb 2017) after a miscarriage in November 2015. Baby Boy due March 2020!
Since I have one recent pregnancy to compare to, I feel like I'm easily discouraged right after confirming ovulation now that I'm back to TTCing. 
When I got pregnant in September, my first symptom was sore breasts, which I started getting at 3 DPO. This is my second month TTC after my miscarriage in November. Last month I already felt like I knew I wasn't pregnant because I didn't have sore boobs - same goes for this month (I'm 3 DPO today and no symptoms). I already feel that I've counted myself out so my TWW is more like a Three Week Wait until I can try again!
I guess I'm wondering if there are any other ladies that feel this way? 
And are there any ladies that did get pregnant again and not experience the same symptoms as they had before?
