Hello, I would like to know if I should see a doctor or if i can continue like this and nothing happens.. thing is: since my first period I am irregular and sometimes it takes about 3 months for my period to come again. Could that mean I will have trouble trying to get pregnant or anything? How normal it is to be irregular? I am health, I do a lot of exercise and my ascending family did not have any problem having kids nor something similar. Please help. I would appreciate any comment. Thanks.
