This is my 4th pregnancy and I'm 6 weeks along. All 3 before have ended in miscarriage. My first I was 7/4 weeks along. Then 5 weeks then a chemical last month. Each time it started with a little brown spotting and the next day full blown horribleness. I had hopes for this one- 3086 hcg and 32.5 progesterone at 5 weeks. Just now I found bright red blood when I used the ladies room. Very light cramping. I'm FREAKING OUT. I can't lose another one! Please send good thoughts for this chalupa, I'm so heartbroken. I'll go in tomorrow to see what's happening but right now I'm going out of my mind. It's hard to hope for the best when you're batting 1000 in the miscarriage department.
