Girls, hi! The doctor prescribed Thrombo-Ass 75, one tablet at night. I'm 11 weeks pregnant and I'm afraid to take this drug. I read the instructions for use and was horrified! After the prescription, I consulted another doctor who also said it's necessary to take it. ? I'm scared for the baby because the instructions say almost in big letters about side effects and what could happen to the fetus. What should I do?
