I'm sorry, that was kind of confusing.
I burn 1600 calories a day with my sedentary setting. I was eating 1400 calories and exercising in order to reach a total combined deficit of 400-500 calories in order to lose weight. I did this up until I learned I was pregnant. I don't think it matters if you lose weight before becoming pregnant. But, again, you probably want to check with your doctor to see what's best for you :)
when you do become pregnant, my doctor and most websites suggest that you up your maintanance calories by 100 for the first trimester and about 300 for the remaining trimesters.
For me I ate around 1700-1800 calories the first tri. and 1800-2100 during the last two tri.
Now see, I do want to mention something.
I am 5'5'', 130 and looking to lose a few pounds. I have noticed that my period came late this month and it seemed to after I had a slight splurge day. I know you can lose your period if you consume too few calories and your body goes into "preservation" mode. So, I would be concerned that there is a reason you lose your period (and perhaps this would affect conception) if you consume too few calories, not necessarily just if you are underweight.
So this is something to think about and look into. As a sidenote I too am trying to conceive and wondering if I should adjust anything...
Too funny that this post is still around. I got an email that someone had responded to it, so I took a little walk down memory lane. I don't recall if I made any adjustments prior to getting pregnant the second time, but the pregnancy (that resulted in a beautiful baby girl who has grown into a very amusing and aggravating toddler) was so terrible that I ended up losing 10 pounds after I gave birth (so I was down to 135 about 2 weeks after I gave birth). I'm at 140 now and no longer counting calories.
At 5'5" and 130, you don't need to lose any pounds, darling. In fact, I would absolutely tell you to maintain your current weight (or get back up to 130 if you've lost any) until you conceive. You can't predict how your pregnancy will go, and you might need all the reserves you can get!
