Hcg 5- update


My predicted ovulation date was the 19th of July. Period due August 1st. I got a faint positive on FRER August 1st and went in for labs that day. My labs came back as hcg 5 and progesterone very low. I was started on progesterone 100mg 2 times a day. I tried a clear blue digital this morning and it said pregnant. I got my labs redrawn today as well. I retested with a clear blue digital this afternoon and got pregnant again. I’m a nervous wreck I will lose this pregnancy. Would you take this as a good sign since I was able to obtain pregnant results with both tests at different times and not just first morning urine? I read that clear blue requires at least 50 to detect pregnancy.
