Answer 1 (slightly misleading)
If the girl gets her period after sex, this means she is not pregnant. If you want to avoid pregnancy, use protection during sex.

Answer 2 (accurate)
Having a period is normal.
However, to correct the answer above slightly, you can still have periods while pregnant. Periods while pregnant are called "spotting" and this occurs as the egg is embedding itself in the wall of the womb.
It means that her period was a week later than predicted and her flow is heavy. It means nothing more than that, there's no mystery here: it's just a late period, no reason to think otherwise.
Yes, some girls do and others are later. Your body decides.
I'm really trying to find the same info but not with much success. If your dog goes in to heat and bleeds her normal week-ish period and stops and then starts bleeding again a few days later - is this normal? I would really appreciate any advise...
Its normal to occasionally miss a period. About 2-3 a year are missed on average.
yes, sometimes later by longer or earlier. it depends on ur cycle (each girl is different)
nothing,it will just begin later than you think
If you had a positive pregnancy test then had a heavy period a couple days later, you may have had a miscarriage. If this happens, you should consult a doctor.
It not likely to do any harm later.
That's perfectly alright. Girls get their period at different ages, and 12 is nearly too late. On average, girls get it when they're about 12.5, which means some get it a little earlier, and some a little later than that.
Usually it happens in the 'preteen' years (10, 11, 12). But sometimes it can happen early or later.
Some girls start early, some start later. I wouldn't worry about it. It's not abnormal.
This sometimes happens. It is nothing to worry about and is perfectly normal. It is probably just that your period hadn't completely stopped
