Hi and

!! This is a fabulous board and we are all here for each other! I agree that starting with the prenatals is a great idea, along with getting in the habit of eating healthy, as if you are pregnant. Every little thing we can do to help our bodies is good.
If you haven't started already, I would also recommend charting your cycles with either taking your temp with a basal body thermometer, using OPK's, or checking your CM &/or CP. Ideally, a combo of all would be the best to figure out what your body is up to and make sure you are ovulating. If you have any questions about any of it, don't hesitate to ask! It can be hard to get into the routine, but once you are in it, it becomes easier and it'll just become part of your life.
Best of luck TTC!!
