Had sex 11 days ago with a condon. my period is 3 days late. cant be pregnancy can it? my first sexual encounter after 2 years. when to test for herp

Some thoughts...: In a woman with regular periods, some causes of a late period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (like birth control pills), hormonal imbalances, etc… Pregnancy is a common cause of a missed period, if sexually active. A home pregnancy test is very accurate 3 weeks after sex or 1 week after missing period.
