Im a breastfeeding mom. since my child birth i got my regular montly period. but this month my period didnt came. weve got sex june 30, nothing follow?

Some thoughts...: Pregnancy is the most common cause of a missed period. If not pregnant, other causes of a late or missed period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (especially birth control pills), hormonal disorders, etc… A home urine pregnancy test is very accurate 3 weeks after sex.
