Covid symptoms and TTC

Hi all. Please respond with your first covid symptoms.

I am in quarantine from being exposed. I am also ttc, but my boyfriend and I aren’t staying together while I am quarantining. My period is 2 weeks late (they’re very very irregular), but I can’t buy tests until next week. I have no pms like I normally would, and I have symptoms of pregnancy.

Lately though, my throat has been a little sore, my nose stuffy, I’m nauseous (I counted it as just a possible pregnancy symptom), and my temperature fluctuates a lot (being cold then hot, I thought it had something to do with nausea). Does any of this sound like covid?? Or maybe just pregnancy? Or a cold? I’m really having a hard time being stuck in my head with all of this.
