Evaluation of Serum Levels of C Reactive Protein (CRP) and Its Correlation With Fetal Ultrasound Parameters in the Prediction of Threatened Miscarriage in the First Trimester

The goal of this observational study is to evaluate and compare in pregnant women with threatened miscarriage in the first trimester. The main questions it aims to answer are: What is the correlation between serum C reactive protein (CRP) levels and fetal ultrasound parameters in predicting threatened miscarriage? How accurate are serum C reactive protein (CRP) levels versus ultrasound in predicting pregnancy loss in threatened miscarriage? Participants will have blood tests to measure C reactive protein (CRP) levels and fetal ultrasound exams to assess parameters like crown-rump length. Researchers will compare serum C reactive protein (CRP) levels and fetal ultrasound findings to see if either or both can accurately predict pregnancy loss in women with first trimester threatened miscarriage.
