I Am Really Scare I Need Some Advice

Yes
I often know I'm fixing to start because my boobs are sore and I'm not able to have children anymore.

That is fairly common. It happens to me every month since I had my daughter 2 years ago.

This is absolutely normal.

Here is a paragraph from a government website:

There are many possible causes for breast pain. For example, hormone level changes related to menstruation or pregnancy are often responsible for breast tenderness. Some degree of swelling and tenderness just before your period is normal.

Mine are slightly sore most months before my period.

With my period, they're just sore. With pregnancy they are painful.

hello ' I do get pain in my boobs too.
dont worry, you get the pain for couple of months and next time is lower back pain right before your period.

it is too much work with twins and taking the 6-year old to school.
good luck M.

Caffeine can cause soreness. My OBGYN told me to limit my caffeine and that really helped.

with no other sympoms it may just be one of those things that changes with each pregnacy it will take almost 2 year before your body is actually ready for another pregnacy

Mine are sore before my period but when I pregnant they hurt ten times as much. This is very normal.

As someone else said, reduce the amount of caffeine you drink especially before your period and the soreness shouldn't be a problem. Mostly for me over the years it's been a tenderness that alerts me more than actual soreness. There were times when I would also get lumps in my breasts which were benign fibroids. They would swell and wain during my system and rarely lasted more than a couple of months. They are also affected by caffeine intake.
