Hi libby, welcome! If you would rather not use opks I would recommend dtd every other day all through your cycle. That way if you do ovulate you won't miss the egg! Having read quite a few soy threads, you can still ovulate anytime, some ladies say it brings their usual ov day forward, others say theirs haven't moved and for a few it delays ov. I'd say if you don't ov at all, if this is going to force you to ov it will probably be cd12-14! Good luck and keep us posted!!
Kitty, I think it's pretty common that soy brings ovulation forward. I wouldn't say it has messed up your cycle, you've just ovulated early. Your lutuel phase should still be 14 days, your cycle is just shorter which is great when ttc! I'd keep using opks for a few days though, just incase that was a surge and not your ov.
I finished taking soy last night and am cd8 today. I'm so pleased I've finished that bit! Was giving me off dreams, lower back ache, heartburn, bloating. I feel just like I usually do just before my af turns up. Which is really odd. Must be something hormonal but don't know what! Ill be doing opks and bding now, really hoping soy doesn't delay my ov.
