Ovulation usually happens at the end of week two. The uterine lining thickens, an egg is released from the ovaries into the fallopian tubes, where it is fertilised by the man’s sperm after sex.
Some women know when they are ovulating – with a one-sided pain called “mittelschmerz” (literally, middle pain), or tender breasts, or a slight temperature increase. You can also buy special ovulation prediction kits, which test your hormone levels to find out when you’re at your most fertile.
At this early stage, your developing baby is a little ball of cells that’s officially referred to by scientists as a blastocyst: It has an inner cell mass that will become the embryo itself.
Try not to get stressed about conceiving – sex should be fun and relaxing. Experiment in bed and enjoy yourself, trying different positions to get good penetration. Anxiety could make it difficult to conceive so the more you relax, the better it is for your body to do its thing.
Don’t feel under pressure to have more sex or to have sex on particular days – there’s still an element of chance involved even if sperm is released at exactly the right time. Sperm count also plays a role in the likelihood of successful conception.
Men who wear tight underpants are likely to have a lower sperm count than men who wear looser-fitting boxers – due to the adverse effect of heat on the testes.
Knowing your family’s medical history is a good idea because about three-quarters of pregnancy complications can be identified early on.
Something else that can be identified early on is a twin pregnancy. If you ovulate more than one egg, then there’s a good chance you will have a multiple pregnancy. Twins occur naturally once in every 89 births.
