I'm 22 weeks pregnant and went to my regular check up today and found out that from my last  ultrasound they noticed a 2 inches blood clot around my lining. My midwife said normal size it's 1-3 centimeters where mines it's two inches. She referred me to a better ultrasound from a more technological hospital. I don't even know what this means or what they would do. FTM and clueless. I would really appreciate any help.
