Around 2 weeks pregnant and have had light bleeding last 4 days. Had major side cramping and went in. HCG count 691 yesterday and sonogram couldn't detect gestational sac transvaginal or transabdominal. Have an OB appointment today to retest HCG. The ER said it may be to early to detect anything with a sonogram. Could I have miscarried or is there still hope?
