I also have a tilted uterus. It took me 2 months to concieve my 1st child and over a year to concieve the 2nd. I was working very hard and stressed when trying to concieve my daughter. The minute I stopped working, I got pregnant w/my 2nd.
Sometimes it takes longer to concieve the 2nd time around. You're working harder, taking care of a little one etc.
You might want to consider having your hormones checked.
Accupuncture and chinese medicine can also address fertilty. My chinese accupunturist cured me of polycystic ovarian syndrome. It took her 2 years and I had to drink some pretty disgusting herbs, but it was better than taking Clomid. Clomid was the only thing hat my obgyn had to offer.
Before accupuncture and herbal medicine, I was hemorraging 3-4 times a year. Very painful. I simply wasn't dropping any eggs, but building up a lining.
I also used a fertility monitor w/the 2nd. The kind that you pee on the stick and put the stick into a machine that reads it. Can't remember the name.
"Women's Bodies, Women's Wisdom" is a great book written by an obgyn. I reccommend it highly. She covers fertility and all sorts of other issues.
