That sucks! It could be a uterine or ovarian cancer or some other problem with them, so see a doctor. It could also be sickness, worry, physical exertion, and even sudden changes in climate may occasionally upset a regular pattern by shortening it or extending it.
either you where to rough, or your early-- both are normal.
ovulation
Usually up to two weeks.
Usually two weeks after day 1 of menstruation is day 14. On day 14 ovulation usually occurs when the Graafian Follicle releases the mature egg into the fallopian tube.
If you mean constant menstruation over the duration of the two months, then no. You should probably see a gynocologist.
menstrual cycle can be as short as 21 days or longer than 35 days. Changes from month to month are also normal. So having your menstruation 2 times a month is normal as long as its around 3 weeks apart. If not there may be other disorders.... My menstruation is 21 days apart and can go as short as 3 days and as long as 8 days. there is nothing abnormal about it. Alot of my friends has the same condition :)
Stress, diet, other hormone imbalances and pregnancy.
Given a regular menses, ovulation normally occurs two weeks after menstruation.
about a week to two weeks if the dog is not normal in about two weeks you should take it to a vet
my daughter has been on her normal period and then 2 weeks later again and it has been over 2 weeks that she has been bleeding. what could this possibly be? is it something to worry about?
You ovulate two weeks before menstruation - thus the soonest you'd skip a period is that first period, two weeks after you get pregnant.
Breast pain is common but not a normal part of the menstrual cycle or menstruation, if you do experience breast tenderness it may be due to hormonal imbalance so check for solutions to this. Your breasts can be tender around ovulation, which occurs around two weeks before your period, and from then up until menstruation or even during menstruation - everyone is different.
