Your odds of conceiving are not as good in your 40's as in your 20's, but that doesn't mean it won't happen. Since the clock is really ticking at this point, I would suggest going in to see your OB/GYN for a pre-conception visit. Your doctor might suggest doing a blood test to measure your FSH just to get an idea of how well your reproductive system is still functioning (regular periods are a good sign, but the blood test can tell you more). She (or he) can give you an idea of what your odds of conceiving are and she can give you suggestions for things you can do to increase your odds. She can also tell you what things you should be watching for and at what point you need to come back for testing if you don't conceive (they say a year when you are younger, but it could be more like 3 to 6 months when you are in your 40's because you don't have the luxury of time on your side). Good luck!
