Day one of your cycle is the first day of your period. This is when your uterus starts shedding the lining it has built up over the last 28 days. After your period is over, the lining of your uterus starts to build up again to become a thick and spongy 'nest' in preparation for a possible pregnancy.
Day 1 of your cycle is the first day of your period, meaning the first day of full flow (spotting doesn't count). During this time, the uterus sheds its lining from the previous cycle. Between days 1 – 5 of your cycle, new follicles (sacs of fluid containing eggs) begin to develop within your ovaries.
Some people get signs that their periods are coming — like bloating, pimples, sore breasts, and feeling emotional. Many people get cramps in their belly, lower back, or legs before their period. These symptoms are called PMS. Not everybody has signs that their periods are about to start.
The ovaries release the female hormones estrogen and progesterone . These hormones cause the lining of the uterus (or womb) to build up. The built-up lining is ready for a fertilized egg to attach to and start developing. If there is no fertilized egg, the lining breaks down and bleeds.
Period symptoms include the presence of menstrual blood, lower abdominal cramps, breast tenderness, and moodiness. Some people experience symptoms like cramping and moodiness a few days before they begin bleeding.
The bleeding tends to be heaviest in the first 2 days – but everyone is different. When your period is at its heaviest, the blood will be red. On lighter days, it may be pink, brown or black. You'll lose about 5 to 12 teaspoons of blood during your period although some women bleed more heavily than this.
“When the uterus is deprived of oxygen, it releases chemicals that may trigger the pain such as prostaglandins which increases uterine contractions. This type of period pain usually occurs during the second day of your period and is termed as Dysmenorrhea,” adds the expert.
On the first day of a period, the level of prostaglandins is high. As bleeding continues and the lining of the uterus is shed, the level goes down. This is why pain tends to lessen after the first few days of a period.
1-day periods happen for a variety of reasons, from pregnancy and breastfeeding to medications and lifestyle changes. One day of bleeding is not necessarily cause for alarm. A “normal” period is what's normal for you. Regular periods last 2 to 8 days, and regular cycles are between 21 and 45 days long.
A significantly greater number of cycles (70.4%) commenced during the night or in the first 4 h after rising, compared with later in the day. In a large proportion of these (29 out of 76), blood was noted to be present on waking, menstruation thus having begun at some time during the hours of sleep.
Unfortunately, it is possible for women to experience worse period pain as they grow older, especially in their 30s and 40s. The unbearable pain can come along with other symptoms such as irregular periods, pain during sex, foul-smelling vaginal discharge.
Unlike the female reproductive system, boys do not have uterus and thus menstruation cannot occur. Therefore, it is biologically impossible for boys to have periods. However, boys during puberty may undergo mood swings or other emotional changes due to changing levels of the male sex hormone testosterone.
Usually, menstrual bleeding lasts about 4 to 5 days and the amount of blood lost is small (2 to 3 tablespoons). However, women who have menorrhagia usually bleed for more than 7 days and lose twice as much blood.
On total, one to seven normal sized pads or tampons per period are normal.
If you notice it only when wiping or can easily absorb any light bleeding with a pantyliner (or even just underwear), it's spotting. If you need a pad or tampon to absorb bleeding between periods, it generally wouldn't be considered spotting.
A fully saturated regular daytime pad may hold around 5 milliliters of fluid. A fully soaked overnight pad may hold 10 to 15 milliliters of fluid.
Fresh blood at the beginning of your period is usually bright red. A heavy flow could be darker, especially with clots. Rusty brown blood is older; what you'll typically see toward the end of the week because the air has had a chance to react with it. Pinkish is probably just a light period.
“Kissing is great if you have a headache or menstrual cramps,” says Demirjian. You may be inclined to wave away advances when you're curled into an achy ball, but the blood-vessel dilation brought on by a good long smooching session can really help ease your pain.
Women usually start noticing physical and mood changes about 1-2 weeks before period bleeding starts. Ninety percent of women have premenstrual syndrome (PMS) symptoms at some point in their reproductive life. Some women have more severe PMS signs and symptoms than others.
It's to care for and be kind and supportive to them. If your girlfriend is hard to be around during these times, and doesn't respond positively to kindness, then it's best to just give her space and leave her alone for a while.
