why do periods come late other than pregnancy
Worried about a late period, but know youвre not pregnant? Missed or late periods happen for many reasons other than pregnancy. Common causes can range from hormonal imbalances to serious medical conditions. There are also two times in a womanвs life when itвs totally normal for her period to be irregular: when it first begins, and when
starts. As your body goes through the transition, your normal cycle can become irregular. Most women who havenвt reached menopause usually have a period every 28 days.
However, a healthy menstrual cycle can range from every 21 to 35 days. If your period doesnвt fall within these ranges, it could be because of one of the following reasons. If you re trying to get pregnant, there s good news: You may still be pregnant. Sometimes, levels of the pregnancy hormone early in pregnancy arenвt yet high enough for a home pregnancy test to detect. One found that only have to detect hCG levels above 25 milli-international units per milliliter (mIU/mL) to achieve the commonly advertised 99 percent accuracy rate.
The writers of a calculated that to detect 95 percent of pregnancies, a test would have to detect levels as low as 12. 4 mIU/mL. But not all home pregnancy tests were consistently sensitive enough to do so. A woman s cycle can vary widely, so if you conceived later in your cycle, your hormone levels may not be high enough at the time of your missed period. There can be as much as a 13-day difference in when occurs, meaning that you may think you are 4 weeks pregnant when you re only two weeks along.
Pregnancy bleeding, recent hormonal contraceptive use, or breastfeeding can all interfere with accurately knowing your dates, as well. If you think you may be pregnant after a missed period but got a negative result on your pregnancy test, wait a few days. Then retest. If you continue to miss your period, be sure to talk to your doctor to rule out any complications.
