I wrote a letter to my birthparents over 2months ago. The letter to my birthfather came back to me saying that it was the address and no forwarding address is available...dead end there. However, at the same time I mailed out a letter to the woman I think may be my birthmother and still have not received a response from her. Should I try writing again or try calling her? I don't want to be pushy but I also need to know if this woman is my mother. I also have some health problems and I know she had similar ones. I have some questions for her about my medical history and need to get answers. What do you think? How much time should I let go by before I try contacting her again?
