What Causes Spotting Instead of a Period?

Verywell / Jessica Olah
Four hormones, including estrogen and progesterone, regulate yourmenstrual periods.
Their levels routinely rise and fall throughout each monthly cycle.
Hormones prepare the uterus for pregnancy and release the blood-enriched uterine lining when an egg isnt fertilized.
The lining bleeds away, causing your monthly menstrual periods.
You may have light bleeding or spotting when the egg attaches to the uterine wall (implantation bleeding).
The cervix may bleed more easily in early pregnancy, causing spotting after sex.
Puberty
Thefirst menstrual periodis often very light with spots of reddish brown blood.
The spotting may last from two to seven days.
It’s also common to haveirregular periodsfor the first few years, which may cause spotting.
Most girls have their first menstrual period around the age of 12 or 13.
However, some may begin earlier and others later.
During this time, hormone production fluctuates, causing changes that affect your periods.
You may have spotting, lighter, shorter periods, or skip periods.
Perimenopause can also cause heavier periods.
Ovulation
Duringovulation, an egg breaks free of the ovary and enters the fallopian tube.
Ovulation bleeding tends to be very light and usually lasts only a day or two.

However, there are some signs to indicate what is occurring.
Spotting is light, vaginal bleeding.
It can be either red, light brown, or dark brown.

Red discharge or bleeding is generally part of your menstrual cycle.

However, period changes may also indicate an underlying gynecological condition.
However, it is helpful to know your cycle.
Try marking the first day of your period on a calendar every month for six months.
Note regularity, light days, heavy days, and any spotting.
If something changes, you will be aware of it and can consult your healthcare provider if needed.
