So I've lost a baby @4 months

Pauline

I lost my baby girl in 2012 on February 27th I was almost 5 months pregnant so my OB has me seeing a specialist for the baby now I have two doctors for my baby they are telling me I'm 20 wks at my ob and 22 weeks at my specialist who do I believe ? My doctors are hoping my pregnancy stays for at least 13 more weeks they fear I may lose my baby as I've already had contractions and bleeding back to back so far I'm doing ok not well very weak sleepy and just blah I'm so scared I don't wanna lose my baby boy 😢💔
