I found out at the beginning of December i was pregnant and i watched my levels rise to almost 700. Then i went in for ultrasound and they seen a thick endometrial lining but that was it then levels started falling last week was 194 I thought well this is my 15th loss. Ive had so many miscarriages and ectopics due to the holiday dr said get blood done today and i did and my level is 200 is there still hope where maybe i had 2 beans and i just lost one? Or is this the unevitable where i have to get the methotrexate shot or worse.
