I have a four year old son when I had him I did'nt see my period for a year.now am trying to have onther baby for a long time now but am not getting pregnant.is it because of that

Is it because of what hun? That you didn't see your period for a year? Did you breastfeed your son?

Have you visted your doctor and had a check up and asked him this question. When you did not have a period for a year what did your doctor say was the cause?

He Say It Was Normal

Not having a period for a year is not normal. It can become irregular because of birth control or breast feeding... but an entire year is not normal.

There are medication that can induce your period, I would go back to your doctor and maybe discuss those options.
