Who ever told you to calm down and relax, gave you the right information. It seems the harder you try the less you achieve. A few years before I had my first baby doctors told me I would probably never be able to get pregnant due to hormone imbalances, a severely tipped uterus, and several other problems. Well guess what, I GOT pregnant and had a healthy baby 2 years later. Then when my husband and I tried for the 2nd one, several specialists said I would NEVER be able to concieve again! After trying for 3 years, we just gave up and decided to adopt. Lo and behold when we quit trying, I got pregnant within 6 months.
Do as you were told, just relax and have fun and don't worry about making a baby and I bet you'll be pregnant in no time. Like I stated, it seems the harder you try and get uptight about it because you're not getting pregnant, the longer it seems to take.
Don't look at your lovemaking sessions as a baby making session and you're likely to get pregnant much sooner, and when you least expect it.
Good Luck and I hope you're pregnant within the next few months!!
