Lisa, while we were ttc I pretty much ate the same, I just cut down on coffee (caffeine) and stopped drinking alcohol. With the pregnancy that I had my miscarriage, the night I got pregnant me and dh were very drunk. lol. But we still knew what we were doing at the time. For the whole time we have been married and before we got married, we never used birth control. We practiced the natural method (pull out) and luckily it has always worked for us. The one time we decided to go all the way (the night we were drunk) I got pregnant. The second time around I was much more careful. I didn't drink alcohol and stayed away from as much caffeine as I could. Ironically, right around ovulation I got a horrible tooth infection, had to have the tooth pulled, was pumped up with novacane and took high dosages of advil and vicodin. I decided to bd with dh right after the tooth was pulled and 2 weeks later I got my bfp. I couldn't believe it. Then I got scared to death that my uterine lining would be too thin due the the high dosages of advil, which is anti inflammatory. Thankfully I didn't miscarry and now have my sweet Sophia, my 4th baby girl (that's including the little girl I miscarried at 19 weeks).
