You most likely conceived in between these 2 periods. I would hazard a guess and say you conceived a few days after your first period but it depends on how far along you are etc. Congratulations.
It most likely means that something is wrong with the way your body is functioning. You should check in with your doctor.
many periods
The popular veiw is 207 years but if you include other periods of Roman peace it lasted for about 350 years.
Most pyramids in Egypt were built during the Old Kingdom and Middle Kingdom periods. These periods lasted from 2686 BC to 1650 BC.
There have been many earthquakes in Turkey that lasted for varied periods. Most of the earthquakes have lasted for about 30 seconds leaving so many fatalities and so much damage.
The Paleozoic Era lasted from about 540 million years ago to about 280 million years ago. It included the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian Periods.
It probably just means you are having short periods. You're just "luck." If you have started the pill or another form of birthcontrol, this could be the reason also. That happens with most birthcontrol.
go to the gyno.
The same as it is now: four 12 minute quarters.
The Cretaceous period was the last of three periods in the Mesozoic era. It lasted from 145 million to 65.5 million years ago.
That depends on the woman. Some women have three-day periods, some five-day and some seven and some have other durations. There's no one set duration. *another answer* It also depends on how long you've had your periods. I got mine when I had just turned 12, and they were really irregular and lasted for different amounts of time. Im fifteen now and I get my periods every four weeks and they last for about 5 days. But when you only just get your periods dont expect them to arrive every 28 days like clockwork :)
Some women experience irregular periods, but if there is a chance you are pregnant, your "period" could actually be spotting.
