That pregnancy was my second. I was pregnant the first time with my gallbladder. After I had my first daughter it seemed as if everything I ate bothered me. After I had my 2nd daughter, things went back to normal, which for me is to fight to stay regular with my b/m (sorry so graphic). That wasn't the case when pregnant.
On another note, a good book for getting pregant is Taking Charge of Your Fertility. I forgot the author. I got pregnant right away with my first, within a month, but the second took longer.
