Hi Tara. I'm sorry for your loss. I'm MaryKay, age 38. I recently lost my first baby at 8 weeks.
Regarding your concern about your parents finding out from another source...who else might they hear it from if you haven't told anyone else?
If you think someone else might tell your parents, I would definitely talk to your parents first. You can ask them to please not spread this information to anyone else because you and your husband want to keep it private, and tell them that you are trusting them to respect your wish for privacy.
Unfortunately, you cannot prevent them from telling anyone but I hope they will respect your request.
Good luck with talking to your parents and again, I'm sorry about your baby.
MaryKay
P.S. Think of it this way...what would be worse, your parents finding out from someone else or the chance that your parents might tell other family members?
