Baby announcements

So I just turned 19 last month and I'm 8 weeks pregnant today... I haven't told anyone about the baby yet which is so hard to keep a secret but I'm so scared because when my 3 year old was born my dr told me I may never be able to carry a pregnancy to term and I've had 4 miscarriages the last one being this past March and I'm so so scared im gonna lose this baby too and I'm scared im gonna tell my family and then boom baby is gone I haven't even told the babies father yet I just don't know what to do im so scared
