I’m so glad you asked this question because I’m been ruminating over the same question/concern.
I will say that I had an accidental CP years back, and the ONLY way I knew I was pregant (otherwise it would have just seemed like a slightly late period) was a DRAMATIC shift in pretty much everything about me.
-Crave and eat mainly lean meats, with fruits and salads
-HATE carbs, and don’t really ever crave or want to eat much dairy
-Work out at the gym after work 2-4 times a week, and one weekend day
All of a sudden, I pulled a 180 and:
-CRAVED all things bread and dairy. Like, more than I’ve ever craveed anything in life
-even the thought of eating meat made me feel sick
-I was so exhausted after work that I had gone directly home every day that week and laid in bed
All that to say…
BEFORE that experience, I was pretty confident I’d be able to carry my healthy, exercising ways all the way full term into any future pregnancies.
I thought, this will be easy – I naturally like healthy foods, I’m naturally petite, and I exercise hard and frequently.
Now. I’m not so confident.
As pp have said, you can never know HOW your body will react to being pregnant, and you can never know if you’ll be able to carry your normal way of being into your pregnancy.
I might sit on my butt and eat nothing but cheetos for 9 months!?!? lol
Another anecdote… I’ve also been trying to “reassure” myself (we are thinking of TTC next Spring, and I’ll be 34) that “I’m petite and lean with a normal BMI, so I’ll likely only gain the 25-30 lbs.”
However, I asked my mom last night about her 3 pregnancies, and I was devastated to learn that she went from a teeny tiny pre-pregnancy 90 lbs to 170 lbs with her first born!!! And that wasn’t an anomaly!! She gained 75 lbs with her second, and 65 lbs with me!
She tried to reassure me that she got back down to her pre-pregnancy weight easily after each one of us, but I can’t ignore the fact she was also in her late teens and early 20’s, while I will be over a decade older.
But, as DH and every PP have pointed out, you really can’t compare yourself to others. There are just too many variables. I understand the impulse – pregnancy is such a huge unknown, and there’s this need to try to arm yourself with as much knowledge as possible to mentally prepare.
My own way of coping is to follow the IG fitness models who have just had babies and see what they did to stay healthy and eat right, how much weight they gain, etc. Katy Hearn is my exact build, so it’s been fascinating watching her belly grow, and I’m excited to see how she handles things post partum.
Thanks to everyone sharing their own experience!
