Trying for number 2

Keri
So my five year old I had with a previous guy, she wasn't planned at all..didn't even know I was pregnant till my girlfriends made me take a test. 
This time around my husband and I are actually trying. I just had my non-hormonal iud taken out (19th) and I have never had a normal cycle. My last period lasted well over a month. Now I'm wondering when will I get pregnant, when will I ovulate....please tell me you go through this too!!!??
