My husband and I just found out we are expecting after being told I did not ovulate to even get pregnant. Itโ€™s been well over a year since I had a period being that my ovaries were covered in cyst. Now my hcg levels were low according to the ER 2445 at four weeks one day. I went back three days later only for my levels to be 2900. So today I had to be checked AGAIN and they are 4595.... still they canโ€™t see anything in the sac. Iโ€™m just so confused and scared to get attached to this pregnancy in case it ends. Anyone else has these issues??
