You worries are completely normal. But 4 months is a relatively short time to have been trying. Some people are lucky and can conceive very easily, and others need some help or time.

My advice would be to see your GP. If you don't have a regular one, try and find one who specialises in Family Planning. Make sure you are comfortable with them and take it from there. Let them know that you have just ceased the pill and that your periods are irregular.

They may do some initial tests for you and see if they can help. If not, they may refer you to a specialist to get your cycles under control to make conception easier for you.

Hang in there..and it WILL happen. Best of luck xx
