What does it mean if I don't have my period regularly and I'm trying too get pregnant?
Have more sex then. It will increase your chances. Just talk to your doctor and make sure that neither of you have any STD's and plan your pregnancy. It helps a lot. Also make sure that you have enough money and living space to support a child.
That maybe you are sick or need to see your doctor about that
I would suggest you visit your doctor to assist you in attaining the goal. He will explain the best time to be intimate to increase your chances of getting pregnant.
