If you suspect that you may be pregnant then you can go for pregnancy testing from your GP or at a family planning clinic, GUM (Genitourinary Medicine Clinic) or at Brook (if you are below 25). You can also buy a home pregnancy testing kit at most chemists and supermarkets. Pregnancy testing should be done following a missed period. Also note that pregnancy is not the only thing you should be worried about. You could be also at risk of contracting sexually transmitted infections (STI’s) and HIV/AIDS and it is advised that you also get tested for these.
Usually a missed period is the very first sign that you are pregnant. Nausea and morning sickness and breast tenderness are other symptoms but these may come much later on in the pregnancy. But you can only be 100% certain by doing a pregnancy test.
