I don't understand the question. Unless you are pregnant after unprotected sex you should have normal menstruation.
no, not normal at all, go to a gynecology specialist
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
I had sex 11 times my first week and my period was EXACT! even after months of sex I have never been late, and the the first period after I started was a little heavier, after that I was fine!
yes
When you are just beginning to get periods (first few years) you may miss a few. It is completely normal. The only other thing is, if you miss periods, you could be pregnant (if you have had sex obviously!) If you havent, its normal
That'd be a bit unusual, but not impossible. Periods are often irregular in the beginning, and stress in particular can upset the schedule.
No, not unless you have had unprotected sex since your last period. Then there may be a chance.
Some girls have irregular periods and that could be completely normal for you. You should keep a record of when you start and stop each period for a few months and then take that to your doctor. They can check you out to see if there are any real problems, but most likely will just put you on birth control to give you a normal cycle.
Of course not. If you like to do that its fine.
It is fairly normal, as teenagers periods are not always regular because their hormones have not fully regulated yet. However, if she has had sex, she should take a pregnancy test. If she hasn't had sex, it might be worth going to see a doctor to check everything is OK, which it probably is. It is probably caused by stress, anxiety, tiredness, travelling, illness or not eating properly.
In normal pregnancy without problem, it is safe to have sex from the beginning of your pregnancy until you give birth.
Periods come and go, I wouldn't worry to much :)
