Treatment Preventive for Pre-eclampsia by Acetylsalicylic Acid in Women Who Underwent Frozen Embryo Transfer

This study is testing whether taking low-dose aspirin during a frozen embryo transfer (FET) pregnancy can help prevent preeclampsia — a dangerous high blood pressure condition that can develop during pregnancy. Researchers are specifically looking at women who conceived through assisted reproduction, where preeclampsia risk may be higher. **You may be eligible if...** - You are a healthy woman aged 18–43 - You are undergoing a frozen embryo transfer cycle (natural, modified natural, or hormone replacement cycle) - You have a confirmed pregnancy at 6 weeks of pregnancy - You have given informed consent **You may NOT be eligible if...** - You already have a known risk factor for preeclampsia (e.g., history of preeclampsia, certain medical conditions) - You have an allergy to aspirin or anti-inflammatory drugs - You have a bleeding disorder or other condition making aspirin unsafe Talk to your doctor to see if this trial is right for you.
