I have a history of bloodclots. I have a protein S deficiency. When I was prengant with Sean i had to take heparin also. Twice a day. But after wards I took the bloodthiner. When you are in labor ask the doctor about pain medication. because you might need it. I know I did. If you decide to breast feed your baby the bloodthiners does not go in the breast milk. by the way i can't spell. good luck with your baby.
