Breasts soreness, over a week

Kellie

Long story short, my normal menstrual has been every 3 months ever since I was 14. Healthy physically but I have over active thyroid. In May, boyfriend and I began trying to get pregnant.

I sometime get breast soreness but rarely and they only last couple days and during my period. It has been going on for over a week and I'm "3 weeks late" for my period (next week I'll be period free for 4 months).

Is this a pregnancy symptom or more than that? I'm waiting until next week to do a pregnancy test. I just need to know how many people experienced breasts soreness during pregnancy.
