Feeling a little nutty!

So, this is only cycle 2 of TTC and I've been taken aback by how quickly I have become OBSESSED with getting preggo. I thought I would be much more laid back, but I think there's definitely a fear of infertility based on experiences of friends and peers. Anyone else been surprised and overwhelmed?!
A little more about me - I'm 31 and currently 12 DPO and anxiously awaiting either a positive test or AF, just so I know! Took a test today with FMU and was negative :(
