Period late or long in between?

Amanda

So my last period was July 10th to 12th I usually don't have them super long and I just started last month keeping track of my periods. I haven't had my period yet this month and I heard if your top far in between periods you must see a doctor to get them where they should be to conceive. we've been trying for two months. I've took 3 test in the last week all negative. I don't have insurance or the type of money to go and see a doctor about if I can or can't have babies until January. My hormones have been crazy making me extremely irritable, I've been super tired, breast have been super sore. could be my periods are very irregular. any advice? And I becoming too far in between to be able to conceive?
