Definitely sit down and have a nice long talk with your GYN and primary care physician about your concerns.
I do have a friend that's been on BC for a long time, and only came off this year when she was legally married to her DH in May. They've been TTC ever since, and no luck just yet... we've been praying for them and sending "Baby vibes" their way, but she just hasn't regulated yet.
My body has changed some, and in other ways it really hasn't changed a lot yet. (heavier bust and bigger belly, but really you couldn't see much of a change otherwise with how I'm built).
I've gotten different answers on the weight gain... in the US/Canada/UK you tend to get a different answer than here in Germany.
The OB/GYN here that I see has said he wants to watch what I eat and how baby develops as well as my weight gain and will tell me if I gain too much. He's reccommended walking, bike riding and low-impact aerobics (water type, treadmill/ski machine) and things like dancing are ok for now... but anything that I could fall or be 'impacted' by something, he doesn't want me to do (animal related riding, high impact sports)... and lifting is ok for now within my normal limit. He said he'd let me know when I need to 'slow down' more... and otherwise my body will tell me.
Babyfit.com I found is an ok resource, and otherwise I read up on what I can where I can.
I haven't gained a lot of weight yet, I think rather I have slimmed up and what weight I have 'gained' has been masked by the baby.
Due to my tendency towards having an eating disorder, I do not weigh myself outside of the dr's office and the occasional trip upstairs to the scale at my inlaws (maybe once a month). I lost weight prior to getting pregnant, then was sick for a month, so I'm back where I was when I got married right now - hanging around 175-180.
The Ideal weight for my height and build is around 170/175.
There isn't a one size-fits all reccommendation as far as weight gain goes either. (One reference:
Mayo Health Clinic)
Mayo Health Clinic says:
My OB/GYN said with what I am eating and how often, so far so good... I asked as some resources were saying I need to intake as much as 3,000 calories a day, and I hardly intake 2,000 on a good day (we don't eat many processed foods and I am not that active) - what did I need to do... and his reccommendation was much the same as the Mayo Health Clinic and other such resources.
I'm taking magnesium and folic acid suppliments, otherwise I eat what I feel a craving towards in moderation, and loads of veggies and fruit. (crazy amounts too!) Water intake is really the biggest concern. One needs to get at least 2-3 liters in a day. One more liter to whatever you normally drink, as it is important to maintain the amniotic fluid around baby.
But seriously, your PCP and your OB/GYN will be the ones who should better know your body, can do a full blood workup and exam and tell you where to start once you are ready to try and conceive.
