I am 31 years old and am osteopenic. I have had multiple fractures without a cause for many years. I am currently enrolled to start in a bone study taking the drug Forteo. I am not allowed to get pregnant during the 2 years. I read that Forteo can cause bone tumors and was wondering what other symptoms/side effects I should be concerned about? Is taking Forteo (for the bone study) my only option? I am constantly stress fracturing without falling or any cause at all, so without a medicine, I fear my body will be 100x worse within 10 years. Do you guys think this is a good idea to participate? I don't have any kids yet, but would like to get pregnant and not sure if I wanna wait 2 years? I'm extremely confused whether or not to fully participate and if it is worth it???!!! HELP!
