Brief summary
The aim of this study is to examine whether treatment with 75 mg aspirin daily compared with placebo could reduce the risk for a new miscarriage. The treatment starts when the pregnancy is detected on transvaginal ultrasound (around gestational week 6+) and continues to week 35/36. The study is a single center, randomized, placebo-controlled, double blind and stratified for age. 400 participants with the diagnosis idiopathic recurrent abortion are enrolled, 200 in each arm aspirin / placebo.
