Hi baby, if you haven't had a period since the beginning of sept. And you are not pregnant, then you are having irregular cycles and you probably aren't ovulating, or other words releasing an egg. It is difficult to catch your fertile days, and your chances of concieving are lowered if you are not ovulating regularly. Usually women release an egg 14 days before their next period and if your partner fertilises that egg and you become pregnant then you should be able to test with a home pregnancy test once your period is due. Alternatively you could request your doctor do a blood test about 7 - 12 days after the date you think you concieved.

Good luck,

suzy
