Is ecosprin safe during pregnancy?

My wife experienced two abortions in last two years. Now she is pregnant (13 weeks). First Doctor suggested to take Hibor 2500 IU every day as soon as pregnancy is detected and taking Hibor 2500 (low molecular weight heparin) every day from last two months. The 13th week scan shows baby growth is very good. We consulted another doctor to whether to take Hibor 2500 injection daily or not. The second doctor suggested to stop Hibor and to take Ecosprin 75 mg tab daily. Is hibor 2500 or ecosprin safe?
