Hi, I am 35 years old and 15 weeks pregnant. Since I had previous attack of cvt and dvt I am asked to take low molecular weight heparin daily 40mg. I am pricking the needle myself. Today when drawing the needle after piercing, I did not relaize that the blod was drwn in the needle. I just pushed the medicine inside an dlater saw that the syringe had blood in it. Is there any danger to me or my baby as the injection was upposed t be given sub cutaneous. Kindly reply as I am very worried.
