Changes of breast are early signs of pregnancy
and if you had pain and tingling
in your breast , it can be that you are pregnant.
If you have missed your periods the chance increase. You can do a home urine pregnancy test using many of the kits available in market (velocit kit, i-can etc ) These urine tests usually come positive within a week of your missed period.
If its negative, these problems of breast can also be explained by a menstrual period which is due which happens because of the hormonal
changes during menses.
Incase you dont get menses and you urine test is also negative, you should see a doctor personally.
