I recently found out I was pregnant from a home pregnancy test. So I went to have it confirmed at my doctors. My urine test there was negative so they did my hcg blood test. I went in two days later for the results and my hcg was only 54 ( I was only 3weeks&3days when they drew blood). So they did a repeat blood draw to see if my levels doubled over 48 hours. I don’t get the results until Monday because of the weekend. I was reading that low levels of hcg can be an early detection of an ectopic pregnancy, but can also vary person to person. Now I am 4 weeks today and had a sharp pain in my right lower abdomen last night that didn’t last very long. Today I still feel a discomfort on the right side but not pain and no bleeding as of yet. This is my first time being pregnant and I am extremely paranoid. It’s driving me crazy. Has anyone had low hcg levels to start with and still have a normal pregnancy? Also has anyone had a transvaginal ultrasound at 4 weeks to detect ectopic pregnancy?
