Dear Doctor Iam 5 month pregnant with twins through IVF. And iam having 60ml Evaparin injection daily as my history consists of 2 to 3 miscarriage Iam also taking ecospirin 75mg twice ,one in morning and one in evening. Now due to high dozes of blood thinners,my nose got bleed. And yesterday my left eye also got red, but my BP was absolutely normal. My area of tension is that, High dear dozes of Hiparin will harm my babies in womb or it is safe . Does the blood thinner crosses the placenta or not. Kindly guide
