Sore breasts... pregnant or period? Hmm...

Emily • Wife, mom, and ttc baby #2.

So I always get sore breaths when I’m pms-ing, I’m about 8 dpo and 6 days from my AF. I’m wondering if any of you ladies have gotten sore breasts around this time but it was because you’re pregnant and not cause of your period?? Or is it too early for this symptom?
