about three weeks
My dogs first heat cycle lasted about 4 weeks.
3 weeks
the best time is 2 weeks after the beginning of your last period, if you're on a 28 day cycle.
This heat cycle lasts for several days up to three or four weeks.
They have the eggs in the last cycle because after they lay there eggs they die 3to4 weeks later
pregnancy is dated 40 weeks from the date of your last period. The first day of your last period counted as day one. You usually conceive during the middle of your cycle so when you find out you are pregnant, usually when you miss you next period you are said to be 4 weeks pregnant but the fetus is only actually 2 weeks old.
No, not necessarily. How far along you are is estimated based on the first day of your last menstrual cycle. For example, if you just missed your period, then you're probably already 4 weeks pregnant!
Hi I am awering your question about a female's menstal cylcle. A female's menstal cycle should last about a week up to two weeks (7-14 days).
It last from about 3-4 weeks before it wares off.
Not usually. It depends on the length of your mentrual cycle, though sometimes its hard to determine how long your cycle lasts esp. if you're young and periods aren't yet regular, but as a general rule cramping 2 weeks before your period simply means you are ovulating. Just before and around Ovulation is the time you are most likely to fall pregnant (roughly 10-16 days after your last period started).
