Regular, unprotected sex is the best way to get pregnant. However, you could try to increase the chances by concentrating your sex life around the times when an egg is most likely to get fertilised.
There are a number of ways you can find out when you are most fertile (most likely to get pregnant). Many pharmacies sell fertility kits – these are a bit like a pregnancy test but you use it before you are pregnant to tell you when you are most likely to get pregnant.
Methods such as monitoring your vaginal mucus and body temperature can also be used to work out your most fertile time. From this, you can work out when the egg is released and when it can be fertilised by a sperm.
Organisations such as Fertility Care Scotland can also help you understand your fertility.
