Wishing you lots of luck for TTC..

Also just wanted to say that using OPKs sounds like a great idea for you so you can get a better idea of when you are ovulating, rather then just guessing, plus looking out for all the other signs too.

I found that with my cycles, I rarely ovulate at the same time each month (sometimes it may be CD 18, or maybe CD 22, or when I conceived my DD it was even on CD 28!). So definitely not the traditional "14 days after your period", and if I hadn't figured that out I would have probably never gotten pregnant! So keep that in mind.
