My left breast is bigger than right normally but the past

Customer Question

My left breast is bigger than right normally but the past couple of days it feels quite heavy and is even more bigger. My period is due and both breasts are tender. I used to have tender breast before period before I had kids but never had one getting much bigger. This is the first time I've had sore boobs since having my first child seven years ago

It's very common to have one breast larger than the other. Usually it's the left breast.

When one breast is larger, it's also common for it to get more heavy and tender when hormones are high.

Most likely all will get more normal once your period is over. Best wishes.
