Watch the clip below to see Sansa Stark getting her first period on the Game of Thrones fantasy/drama TV series. The event is traumatic for Sansa because it means that she will now be forced to marry someone she hates – therefore Sansa and her servant frantically try to hide all traces of the bloody bed-sheets!
All female placental mammals have a uterus lining (“endometrium”) that builds up when the animal is fertile. If the egg is not fertilized, most mammals reabsorb this lining into their uterus (“covert menstruation”), however a few mammals, including humans, shed this lining outside of their bodies (“overt menstruation”).
Humans have “concealed ovulation”. Concealed ovulation is the lack of any perceptible change in an adult female (for instance, a change in appearance or scent) when she is “in heat” and near ovulation. Continue reading

Over the last six months I’ve started to experience light spotting a couple of days before each period begins. The spotting is very light and is usually a brownish colour (or sometimes red). Continue reading
I bought my first menstrual cup almost four years ago – a small soft Yuuki menstrual cup – and it’s been fantastic (see my review here). As you can see that cup has become very stained! I don’t mind the stains at all, however if I wanted to I might be able to remove them by soaking the cup in a vinegar/water solution. I recently bought another small soft Yuuki cup. I’ve uploaded a few pictures of my old & new cups (side by side). Continue reading
The video below is a hilarious (and oh-too-true) song about menstrual pain! It is a parody of The Cranberries “Zombie” song. Lyrics are below the video for you to sing along
I’ve heard that dolphins can tell when a woman is pregnant (sometimes even before she knows herself), and start acting strangely around her. I wanted to know if dolphins acted any differently around menstruating women as well. Unfortunately not much seems to have been written about this (and I couldn’t find any actual research or studies that had attempted to answer this question). Continue reading

Stem cells are a type of biological cell that have the potential to become any cell in the body, therefore they can be used to repair damaged tissue. Stem cells come from two main sources: embryos or adult tissues. Embryonic stem cells can give rise to virtually any cell type in the body, but they are controversial because conventional procedures for obtaining them involve the destruction of an embryo. Adult stem cells, such as those found in bone marrow, do not pose the same ethical concerns, but they have limited powers and collecting them can require invasive procedures.
In recent years scientists have begun studying the stem cells that are present in menstrual blood (stem cells appear to aid in the rapid expansion of the uterus lining during a woman’s monthly period). Continue reading
A baby girl is born with 1 to 2 million oocytes (human eggs) in her ovaries. When she hits puberty all but about 300,000 will have died before becoming mature eggs. Of these, 300 to 400 will be ovulated during a woman’s reproductive lifetime. By menopause all of the eggs are gone. A baby girl is born with every egg she will ever shed, and more. Continue reading
