2nd month TTC #2.

This week will be my 2nd month ttc baby #2. With baby #1 with tried for one month and bam we were pregnant, but this time no luck. I feel more stressed and nervous this time around then last time. Why is that? I feel like I don't know what I'm doing, confusing symptoms and then getting a bfn. Last time I knew right away that we were expecting. Why is this time harder ???
