Hey Jen, I've definitely had sore boobs more on some days compared to others. I'm guessing it'll be to do with the increase of hcg every few days
I'm 6 weeks today. Mine were super sore until 2 days ago. And now they're about half as sore as they were. I've also lost my constipation but gained cramps and a headache. Praying they find a HB next week. My first 2 pregnancies they did not.
