Good evening I hope you are feeling a little bit better.
Did or does your doctor know you are off your meds and are trying to become pregnant? If not let your primary care physician know. He/she might suggest a multi vitamin with folic acid and perhaps a small does of calicum or just the sm chewable (tums).
Pergnancy is hard, as you already know, there is very little we can do with our bodies before / during / after bringing children in to the world. If you plan on breastfeeding (like I did) the process can take up to 4 yrs before you get your body "back".
I am unsre of what to suggest as you have chrons. Sorry cant help tooo much.... But WWOOooOOOooOT! I loved that stage of my marriage *sigh* Its a lil jelousy there but all good hearted! Grats!!
