Hoping to find some ladies in a similar situation to either help keep the crazy at bay... or provide company to safely let it out! 
DH and I had planned to wait until May-ish to start trying for #2. Our DD is 15.5 months and we are due to complete on our new house next month so wanted to wait. I am still BF but only a couple of times a day. Periods returned at 8 months and have been every 29-33 days since. Downloaded the sodding Ovia app last month, "just to start monitoring my cycles"... instead I am already devoting an unhealthy amount of time to staring at it and subsequently became fixated about DTD on my ovulation day (usually around CD18-20). Successfully managed to seduce DH during DD’s nap this weekend on CD18 and am now descending into madness checking CM and wondering about every minor twinge! 
So I guess we are now officially TTC! The madness, upset and hoping begins again!
Please tell me there are some of you in the same boat?!
