Not necessarily. Some people have irregular periods and can miss them for this long. Stress can be a contributing factor among many others.
Nope
the birth control is probably it.
no
I wouldnt say irreuglar periods are a sign of pregnancy its usually actually missing a period for about 2 , 3 or even 4 times(months) in a row. Irregualr periods mean that your body is just developing differently. I reccomend Yaz birth control pills , they regualate ur periods very well.
amenorrhea
a trimester is 3 months of your pregnancy. there are 3 trimesters in a pregnancy. 1-3 months, 4-6 months, and 7-9 months.
NO
As in bleeding all the time for 3 months? You need to go and see the doctor. If you mean that you had your periods for 3 months (ie as normal, not lasting for 3 months) and then they didn't arrive on the fourth month, it depends on a few things: . Were those three months your first periods? . Have you had sex? . Is it a combination of both? If they were your first periods and you have NOT had sex, it is not anything to worry about. Periods take about a year (sometimes longer) to regulate If you have had sex, you need to take a pregnancy test If these were not your first three periods, take a pregnancy test if you've had sex and if not, see if you get your next period, and if not, go and see the doctor
