Overanalyzing everything! 😕

I miscarried our first pregnancy in September and this month was our second month of TTC.  Now that I know what it feels like to be pregnant, I feel like I'm driving myself crazy trying to figure out if I'm having symptoms again.  I took a test this morning and got a BFN, but my boobs are a little sore today and I've felt nauseous all morning.  My temperature has stayed elevated for longer this month than it did last month (I'm 9 DPO) but I feel like I'm overanalyzing everything.  Anyone else have trouble not getting your hopes up with every little symptom??
