I was watching a food video by a nutritionist today which happened to mention that if you are ttc your bmi should be between 22 and 24, which is 140-145 lbs for a 5’ 6” female. I’m 5’6” and I weight about 20 lbs less than this and I’m wondering if it could be affecting my fertility. I don’t restrict my diet at all, and eat what I want, although I also weight train a few days a week and walk or bike 2 km each direction to work daily. I have a generally healthy diet and cook the majority of my meals at home. I never thought weight would be a problem since I consider myself and my relationship with food healthy, even though my medical check classes me as underweight. I know my mom had to gain about 15 lbs before she was able to get pregnant with me, so I’m wondering now if I should try to gain some weight. Does anyone have any experience needing to gain weight to conceive? Or any other slimmer ladies have success with ttc? Just looking for other people’s experiences.
