Bleeding during early IVF pregnancy can be worrying, but it is actually quite common and doesn't always mean there is a problem. However, you should not take the medication you mentioned (which contains ethamsylate and tranexamic acid) without consulting your doctor first. While these active ingredients are sometimes used to manage bleeding, self-medicating during the first trimester is not recommended. Please contact your fertility specialist or obstetrician immediately. They will likely schedule an ultrasound to identify the cause of the bleeding and ensure your baby is safe, as well as adjust any hormonal support if needed. Rest as much as you can right now.
