Am I losing too much weight? Also diet vs. exercise question
Delurking yet again. We will finally FINALLY start to TTC end of October 2016! I'm obsessed since I've wanted a baby for 10 years, and even though I'm happy with the decisions we've made before TTC (career changes and financial security, and getting DH ready to be a father), I am so excited to finally just get going on seeing if we actually can make babies! For numerous personal reasons I've decided to try and add a light pink sway to my TTC planning - I'd love a son as awesome as DH, but my heart is set on a girl for our first (and possibly our only). The only things I've done so far starting in June are switching to nearly-vegetarian diet from a more "flexitarian" diet (I did eat meat about once a week and fish once or twice a week before; now I'm mostly eating legumes, grains or soy for protein, low-fat dairy or eggs a few times a week and am allowing myself clams or oysters no more than twice a month, for a little lo-cal B12 boost), doing only daily folic acid and a teensy amount of iron once a week(I have a history of low-iron stores and low vitamin d (though my doc tests me in Feb, which obviously skews my D #s), but I've spent the spring weaning myself off the D - summer is my "happy" time of year, so I'm not feeling any ill effects from no supplemental D), and dropping my weekly strength training (though I know Atomic disagrees on this - honestly this is just a time-saving move for a stressful job situation and I'm hoping to reintroduce low-impact strength training 1-2x/week mid-pregnancy). Finally, I began skipping breakfast (only having black coffee) and avoiding oats in June. In April and May I started weighing myself weekly because I knew I was starting at a low-normal BMI. I'm a little surprised to find I've lost 10 lbs in one month! I'm a beanpole, so this only shifts my BMI down to 19.4 from 20.9. But as someone who's never conceived before and is turning 34 in August, I'm a bit nervous about starting out TTC underweight and/or undernourished. Also, I'd really like to add exercise to my sway, but I'm guessing I've got to up my calories to do so. I haven't counted calories and haven't stopped myself from snacking after lunch/before dinner, so I'm guessing I'm at 1700-1800 cals/day (pretty sure I was 2000-2200 when I was eating breakfast and high-fat dairy - I haven't tracked calories recently but I have a good idea from previous times where I've tracked them). I think given my activity level I won't drop too much more weight if I just keep things where they are (I've certainly been this skinny before in my life), but I'd like to try and add 30 mins of power walking or jogging in the morning to my 30 minute walk to work, to equal 60 mins cardio total (and do a 60 minute walk, jog or bikeride on one of my days off from work every week, to equal 6 days of 60 mins cardio). I'm going to continue to weigh myself weekly, but I'm not sure if there are any other tweaks I should do before upping my exercise, or if I shouldn't bother? Is 60min frequent cardio + higher cals a better sway tactic than lower cals without formal cardio?
And yes, I know some ladies on here have conceived at very low BMIs. Personally, I'm just not comfortable with dropping below 18.5, which for me is only 7 lbs away. I'm tracking BBT now, to see if there's any wonkiness in my cycles (when I ovulate and luteal phase normalcy, esp since we hope like everyone to get a BFP quickly!). So yeah, any input on cardio + higher cals vs. lower cals without cardio would be appreciated. I've seen Atomic frequently reference cardio 6-7x/week as one of the best "simple" sway tactics, but how important is it for those of us who have fast metabolisms?
