I went to the ER today because I've been bleeding for the past 3 days and it was getting a little heavier no clots or extreme cramping. According to my first day of my last period I'm 5w5d. They did a Blood work and my HCG levels were 120.6 saying I'm only 3wks. Also had a vaginal ultrasound and they didn't find any sac. But said it would be way to early to even see anything, or if I already had a miscarriage. Told me to go back to my Obgyn next Monday to see if my levels have gone up.
