Lots of things can cause abnormal menstruation. I have polycystic ovarian syndrome (cysts on my ovaries) which causes me to have hardly any periods (between 2 and 4 months, and even went a year without once). Other contributing factors can be stress, weight, activity, and many other things. And yes, it can effect you ttc. POS is actually one of the leading causes of infertility. I was lucky to have my children when I was young cause it would be extremely difficult for me now if I wanted to try again.
You might see if anything in your life has gotten overly stressful, or anything else has really changed... like activities, or diet. If nothing has changed that much then it might be time to go ask a doctor. Hormonal tests can rule out of a lot of things, that is how they discovered my problom. A regular papsmear can also rule out a lot. So two tests is worth the piece of mind to know everything is okay.
