Look I have had my iud out since August 31. I have not gotten pregnant and every month that I get my period I cry because I am so worried that it won't ever happen for me. I'm 36 years old and how about if it just doesn't happen. I have one son who is 8. I am blessed to have him but I want another more than anything and it seems like it's happening for everyone around me lately. It really is making me depressed. How long should I keep trying until I speak to a doctor?
