I began miscarrying at 5 weeks on September 14th. My HCG on the 16th was 837, dropping to 504 on September 22, and 304 on September 23. On September 26th I had severe cramps and passed the tissue/ baby. I have had spotting since and some light bleeding. I took a final test on the 1st and it was negative. Yesterday I noticed the shooting pain in my breasts and a low, stretching feeling in my andomen. I should "expect" my cycle to begin tomorrow but I took a test and had a faint line. I'm aware I may have HCG left in my urine but that seems unlikely as my levels dropped rapidly. I took a clear blue digital test tonight and it came up as 1-2 weeks. Has anyone had a similar experience and can offer some insight? I'm travelling and hoping to see a doctor tomorrow. I don't know if it's possible to be pregnant this quickly...
