try googling fertility charting, basal body temperature, and ovulation predictor kits. You can find lots of information on how to chart your fertility and determine when you're fertile each month. I've also heard the book "Taking Charge of your Fertility" is good. If you are having trouble getting pregnant the best thing is to talk to your Dr., as the previous poster said.
There is no way to tell by looking at you. You need to see a Dr. best wishes to you.
