I'm 17 with a late period and 4 negative pregnancy tests - what next?

Thanks for writing in… We are not a medical service, so my only advice can be that you visit your GP for further investigation. It’s true that some women do not show up on pregnancy tests in the early stages, so you should not rule out pregnancy until you have been examined by a doctor. However, it is possible that you are missing periods for other reasons. You should seek medical advice as soon as possible. If an unplanned pregnancy is detected, then you can visit your nearest centre to talk through your options and how you feel about your situation, so that you can make an informed decision about your future.
