I'm only 12 dpo and my breast are really sore. Normally before my AF I do not have sore breast. I've been emotional and last night I woke up at midnight angry. Dh and I bd 1 day before o so I thought that there was going to be a low chance at conceiving. I know that hormone changes can cause sore boobs. Is this just a AF coming thing or possibly pregnant thing? Thank you!!
