Yes, more or less. It's more coincidence really.
No, it can start at any time. You might have thought your period starts on the first of each month because periods are "monthly," but this just means that the average woman gets their period every 28 days. Once you get your first period, it will take about a year for it to regulate. Once it does, you will get a period around the same time each month, or you will have about the same number of days between each one.
A menstrual period typically occurs once a month, although the cycle length can vary from woman to woman. Each menstrual cycle lasts around 21 to 35 days, with bleeding usually lasting around 2 to 7 days.
If you experience two periods in a month, you may ovulate twice, typically around 14 days before each period.
Unless you are pregnant or have had a hysterectomy operation, you should have a period each month (28 days perhaps).
They lay up to 7 eggs each month.
You have a period roughly every 28 days however it varies depending on each woman.
Get a small pocket calendar. When you begin your period put a little x on the date and do that everyday you have your period. Do the same thing each month and you will see a pattern after 2 or 3 months. This will also help you know when you ovulate since that happens in/around day 14 of a 28 day cycle. Keeping this info each month is valuable to have and to know.
around 57
they probably walk around and find each other
usually you will start the pill the Sunday after your period begins. this will regulate your period so you will get it about the same time each month
Your ovulation is from one side each month, and each ovary runs on its own cycle. Usually they match and you get your period at the same time each month. This means that if your period is every 30 days, your right ovary drops an ovule (egg) this month. 30 days from now, your left ovary will drop one. 90 days from now your right ovary will activate again and drop an ovule. And so forth. However, if one month you ovulate early, meaning you get your period early a few days, the next month you will ovulate on your original schedule on the opposite side, which means that period will feel late to you, when in reality it is running on its own proper schedule.
Females are born with their reproductive organs, including the eggs necessary for reproduction. When a female reaches sexual maturity, typically around puberty, her ovaries release an egg each month during the menstrual cycle. If this egg is fertilized by sperm during sexual intercourse, pregnancy can occur.
