Finding your fertile window At ovulation, an egg is released from the ovary.
If there is sperm waiting around at that time, there is a good chance it will be fertilised and grow into a baby.
If you don't have enough iron, your haemoglobin levels will drop.
This is called iron-deficiency anaemia, and it can be harmful to your baby if it's left untreated.
If a woman has sex six or more days before she ovulates, the chance she will get pregnant is virtually zero. If she has sex in the three days leading up to and including ovulation, she has a 27-33 per cent chance of becoming pregnant.
From that point, the probability of pregnancy declines rapidly.
But the likelihood of conceiving is dramatically increased if sex occurs in the three days leading up to and including ovulation.
The fertile window varies depending on the length of a woman’s cycle: the time from ovulation to the next period is approximately 14 days, irrespective of cycle length, but the time before ovulation varies between women.
Eating plenty of iron-rich foods such as red meat, poultry, fish, lentils, leafy green vegetables and fortified cereals, will help ensure your iron stores are healthy.
