Baby fever

Sometimes I want a baby so badly, it eats me up inside! Its all I can think about. My long-time SO and I use the pull-out method only (we are both STD free, in love, and could survive if we had a child). We want a baby eventually, but we both know that its best for our careers to wait 2-3 more years. Even though the logical part of me knows this, I still want to get pregnant so badly! I secretly hope AF doesn't come each month. We thought I was pregnant once, and when it came back BFN, I was secretly devastated. What do I do?! I can't keep ignoring the logical part of me...but love and mother nature are driving me insane with baby fever! Can anyone relate??
