A space forms inside the morula (the embryo at its early stage of development), as some cells clump together in the middle, and others are pushed to the edge. The morula is now known as the blastocyst. By now, the blastocyst has made its way to your womb and is ready to embed itself in the endometrium - or the lining of the uterus. At this point, it's still not visible to the naked eye. The cells of the trophoblast put out tiny projections like tiny little fingers, which are called the chorionic villi. These manage to burrow into the endometrium, breaking it down to help the embedding process. The embedded blastocyst now starts producing a hormone - chorionic gonadotrophin. This stops you having your period and shows in your urine. You're pregnant - yay!

Some women have a very slight bleed at this point, called implantation bleeding. But don't worry, it's much lighter than a period and happens before your period would have arrived. Try a home pregnancy test - you might be pleasantly surprised!
Your relationship: trying to conceive can put a lot of pressure on a couple. Spontaneity, romance and enjoyment can all dwindle in the focus to make a baby. If you feel this is happening, make an effort to be loving and work together. Maybe get away from it all with a short break? Couples often conceive when they're on holiday and more relaxed. Go on... book those tickets!
