You may be experiencing some non-menstrual bleeding, which can be normal. Especially if you are taking Birth Control and have missed a dose or two. Cycles are not always regular, and menstruation can occur every 3 to 8 weeks. If your bleeding continues for more than a week, it would be prudent to seek medical attention.
Yes, it is completely normal for your cycle to start a few days earlier than you predicted. Menstrual cycles are never exactly the same, and anything up to a weeks variation from your avergage menstrual cycle length is totally normal.
Depends...per WebMD (http://women.webmd.com/tc/normal-menstrual-cycle-normal-menstrual-cycle), "The menstrual cycle is measured from the first day of menstrual bleeding, Day 1, up to Day 1 of your next menstrual bleeding. Although 28 days is often cited as the "regular" cycle length, only 15% of women actually have such a cycle." * A teen's cycles tend to be long (up to 45 days), growing shorter over several years. * Between ages 25 and 35, most women's cycles are regular, generally lasting 21 to 35 days. * Around ages 40 to 42, cycles tend to be the shortest and most regular. This is followed by 8 to 10 years of longer, less predictable cycles until menopause.
Female dogs do not have actual menstrual cycles. Instead, they have estrus cycles. These cycles consists of proestrus, estrus, diestrus and anestrus. The number of cycles varies by breed with most breeds cycling two times a year,
1 your uterus wall builds up for an egg to be planted 2 your egg travels from your ovary down the Fallopian Tube into the upper part of the uterus 3 when the egg isn't fertilised your uterus's wall of extra tissue breaks down and you'll bleed, this is a period
It could mean that you are pregnant. If you have not settled into the normal 28 day cycle you could also be fine. Try a home pregnancy test.
The first day of your period is day 1 of your cycle, you count from this day up until your next period - this is one cycle. You should calculate the average of your last 6 cycles; add together cycle lengths from your last 6 months then divide by 6 to get your average. Web sites or phone apps can do this for you. The average menstrual cycle is 28 days but everyone is different and up to a weeks difference from your average menstrual cycle is completely normal. It's worth noting that irregular cycles are normal throughout your teens, and things such as ill health, stress, or some medications can effect your cycles. Learning to recognise changes in your body throughout your cycles can help you determine when your period is due, even if your cycles are irregular.
back to normal menstrual bleeding
About once a month, the uterus grows a new, thickened lining (endometrium) that can hold a fertilized egg. When there is no fertilized egg to start a pregnancy, the uterus then sheds its lining. This is the monthly menstrual bleeding (also called menstruation or menstrual period). The MC is measured from the first day of menstrual bleeding, Day 1, up to Day 1 of your next menstrual bleeding. Although 28 days is the average cycle length, it is normal to have a cycle that is shorter or longer.
No not at all. You are only supposed to have 1 a month
A woman's menstrual cycle averages around 28 days. Not every woman has a 28-day cycle though and not every woman's cycle can be counted exactly the same every month. Some women may only have a 20- or 25-day cycle while others may have 30- or 35- or even 40-day cycles. It depends on the woman's body. The actual length of time that a woman menstruates (or has her period) is typically around 5 days...although, again, it depends on the woman. Each month may be different with some really heavy months or some really light months.
The menstrual cycle begins Day 1 of your period, about half way through the cycle you ovulate and the last day is the day before your next period starts. Day 1 begins the cycle all over again. The last day of your cycle tells you the length of your cycle, on average between 24 and 34 days, although longer and shorter cycles are still "normal".
Whether a heavy period is a problem or not depends on how heavy the menstrual flow is, some women do have heavier periods without it being an indication of a health problem - it's also normal for teens to have heavier flow. If you leak through the most absorbent tampon, menstrual cup, softcup, or menstrual pad within 1 hour then it is a concern that you should discuss with a doctor.
