I didn't really take any notice of my ticker when ttc. I've never been able to do the relaxed approach either, I went for it like a military operation both times
I'm not very patient! I used this website to help

It helps if you know what your luteal phase is but if not I just put in 14 days and it gave me a rough idea of when to try. I used opks though because your body will never do what you are expecting and I liked to know when I was ovulating. Oh and I also did the sperm meets egg plan
Although I'm not patient it worked both times! xxx
