Hi, im 24 and been trying for a baby 3/4 times a week for 6 months, still no lucky yet. My periods are roughly every 3 months, I am worried there may be something wrong with me. I told the nurse i had irregular periods about 1yr ago, she didn't seem concerned. With these major irregulaties how/when am I supposed to test for pregnancy. Im driving myself crazy never knowing. please help!
