please pray for me girls...had a miscarriage

Yesterday I was about 6-7 weeks along and I had my regular scheduled OBGYN appt to see if there was a heartbeat. Well I jumped in the shower to get ready to go and I noticed some spotting, period like! By the time I got to the drs office which was about 2 hours later I was bleeding. The dr did a sono but we didnt see anything, she drew blood to check my hormone levels and said if I stopped bleeding and my levels were high then I was fine but if I continue bleeding then I'm miscarrying. I woke up to what looks like my period this morning. Me and DH are so sad. The dr. said the good thing is my body is taking care of it on it's own so we can try again asap, but i'm still sad that this is even happening and so scared that it could happen again! I'm just asking for some prayers
