I am 42 years old,trying to get pregnant,i do have a 15 year old daughter,did all the tests,my husband did a semen analysis his fine too,what could it?

Common: It's very common for a 42 year old woman to have trouble conceiving. I suggest if you're very enthusiastic about having another child that you should see a fertility specialist.

Inadequate info: The common numbers suggest it takes an average of six months of trying to achieve pregnancy (for first timers). You have been able to in the past so chances are you will again. If it has been more than a year of trying, seek the advice of a fertility center to clarify your options.
