Hi. I Have A Problem And I Hope You May

Hi. I have a problem and i hope you may help me. I took Utovlan for two weeks because I went to holiday and when I came back i've stoped taking and my period hasn't come and i've done a test and it was positive. I started bleeding on the 8th and it didn't stoped until now. I've done a scan and the doctors said the baby is ok and they said to go back to the hospital if the blood colour changes or if the bleeding gets worst. The problem is that during two days the bleeding has stoped and after that it started again and the colour has changed to light red. I am really upset because is been 3 weeks bleeding and nobady gave me any explanations. Hope to get some answers! ☺
