Worried...

I had a silent miscarriage in February.  This was our 3rd pregnancy (3rd child).  We have 2 daughters.  It was an unexpected pregnancy and very unexpected loss.  We waited the 2 cycles the doctor recommended before trying to get pregnant again.  On Saturday, my cycle was 3 days late so I woke up and took a pregnancy test. The test was postive!  I thought I would be more excited, but I'm actually worried, nervous and scared.  I want to tell family and friends, but I'm too scared to tell anyone.  (My husband knows and that's it).  I feel so alone with all my emotions and feelings.  The doctor won't schedule appointments until week 8.  I'm 4 weeks 4 days now.  I have about 3 weeks before I can be seen.  I called today to make an appointment at a local clinic to confirm pregnancy.  I'm praying and trusting that God will provide me with some peace and comfort.  I could use prayers from others as well.  Please pray for a healthy pregnancy and baby.
