yes, because your body is getting back into the habit of your cycle. its sorta like going through puberity again in a way, but much faster to get back on track.
Yes.It is normal but it is not your true first period. It will come later.
Stress
Well, I got my first period when I was about 11 years old. And then a little bit of spotting again a month later. Then, Didn't come again for about a year, Now I have it regularly. So my best guess, Would be no, Its completely fine. Yep, I agree with ^! I had my 1st period when I was 11. Your periods aren't suppossed to be perfectly normal for the first 2 or 3 years! If you spend alot of time with another woman, your periods might start to sync, (You probably know that) but If that woman is about to experience menapause, then it might throw your cycle off!
Its normal to occasionally miss a period. About 2-3 a year are missed on average.
it's not normal, but depending on your age, it can happen. If you are concerned about pregnancy, first of all get protected next time and second, get tested.
Yes, it is normal. It can appear at anytime, as early at age 10, or later at 16. It can even appear earlier or later. If in doubt, contact your doctor.
When I miscarried I was told to act as that was the first day of my period so in effect I could conceive 2 weeks later as within a normal cycle
It is possible to become pregnant 3 months after delivering a baby, but the gestational period is generally 9 months in normal healthy pregnancies.
Normal
Your not pregnant because the egg released obviously so the sperm didn't get attached so no your not pregnant
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.
Yes, this is normal. Intercourse doesn't effect menstruation at all so it has no relation to your period, when your period starts is dependent on your menstrual cycle - sex doesn't effect this.
