Hello L.,
I just recently had my second child. My son is now 4, so I see that the time is right for you to have another child and give your daughter a sibling. When I starting trying to conceive last summer, I did not think about it at all. I did not plan sex nor think about the whole process. In other words I did not stress over trying to conceive. I feel the whole process of thinking and worrying about getting pregnant gets ladies worried and stressed. Stress is a major factor that prohibts women from getting pregnant. So please don't stress over it, allow it to happen on its own and it will. Give yourself some time and relax, enjoy your daughter and allow mother nature to take over. We all know the phrase practice makes perfect. If however, 6 months have passed and you are still not pregnant and am starting to worry about it, then take the next step that is comfortable for you, such as what the other ladies have suggested. Keep in mind also that there is a month when u may not ovulate at all. Basically, relax and enjoying just being intimate with your husband. That is what I did and it worked for me. This is my recommendation.
