nothing,it will just begin later than you think
you can if you are just starting. it's normal for an irregular flow.
Most probably not, even with such a short period.
If you ovulate around day 14 and have regular periods, by LMP (last menstrual period) you would be 5 weeks - the actual age of the embryo would be 3 weeks.
You conceived approximately 3 weeks before you realized your period was late.
During pregnancy you should not have a period. So yes.
No. You have to have fisical connections with a male a few weeks before your period so you will become pregnant. But if you don't have it, and just wait up to 3 week after it is late and go see a doctor.
youre probably a late ovulator. doctors go by a standard 2 week ovulation calendar meaning most people ovulate 2 weeks after the day they start their period. im also a late ovulator. i ovulate 3 weeks after the day i start my period so youre probably 6.3 weeks
well, first of all, it matters how many periods you have had. if this is like your 1-6 period then it is normal to start a little later or earlier. if not then i would say you would know when you are about 2 or 3 weeks late.
It is possible. I suggest getting a blood test done at the doctor's.
Pregnancy tests are not always right. Plus 3 weeks is quite a bit of time, you should go see your doctor, you will get a more accurate test.
4 weeks and 3 days as long as you have a normal 28 day menstrual cycle. It could be less if you have an irregular ovulation cycle.
Periods can be and often are very irregular in young girls up to 3 years after their first period. After these 3 years, if periods are still extremely irregular, a girl should see her doctor.
