I had my period on time and normal, it stopped. About three days later I started to bleed again, this time I was passing litlle blood clots. I went to the hospital and they told me I could be going through a miscarriage, did a pelvic exam and an ultrasound. The doctor told me I had to wait that the ultrasound did not show a baby. The bleeding is oly getting heavier and the clots a little bit bigger. How long is this gonna last, or do I need to go back to the ER and get checked again?!
