Hello I have been trying to have a baby since march and still no luck what could be some of the reasons that I'm having a hard time cauuse everyone in my family had kids as many as 13 what is my problem

It can take years sometimes, after a couple of years you can say you are having a problem, not a few months.
But it is never a bad idea to have a complete medical checkup for you and your husband also.

When was your last medical check up? Your husbands? Have you ever been on birth control? If so, what kind and for how long.

Without ever being on birth control it can take healthy couples at least a year of actively trying to become pregnant.

My check up is this Monday and my husband is fine he has two childeren from his previous marriage and no I'm not on any birthcontrol and never have been

Just because he has had children in the past, it doesn't mean that he is still good child bearing position. Time changes things sometimes. Not saying that he is for sure the reason, just saying not to rule it out. Since you have only been trying for about 6 months now, I wouldn't be worried. It takes most healthy couples up to 12 months of trying to conceive naturally, before it is suggested to see your doctor about your fertility.
