From your other post I gather that you are 18 years old? If you have only really been trying for one month then I would give it a while to try and get pregnant.. it would not be unusual for you to be trying for a year when you are 18 years old.. by this I mean actively trying every month until you fall pregnant... IF you havent fallen pregnant after trying actively for around a year then I would definitely go and see a doctor and have some tests done. I agree with the other poster that just because your mother was ok in having four children it doesnt mean anything. I have been trying since September 2006 but I am 31 so my age may be playing a factor.
With regards to your other post about you getting married first, it may be worth waiting a while if you are going to struggle for money as you are still very young. It may be worth being in a good financial stable position so that your baby won't have to go without anything and that you can also support yourself. You said you would have to turn 22 years old so it may be worth waiting but again, thats at your discretion.
Either ways I hope this has helped and wish you the best of luck in whatever you choose to do
