I have had an IUD for almost 5 years, I started bleeding and passing clots a couple of weekends ago... Went to have the IUD removed and found out I was about 6 weeks pregnant. I thought I had miscarried but when I had a sonogram the same day there was a baby with a heartbeat way up in my uterus. Also the technician told me that I released two eggs so they think I may have miscarried a twin. I went in the next day to have the IUD removed and had a little brown discharge for about 2 days. I also had a couple of beta screenings. One on 09/5 (11,178) and the other on 09/07 (13,293). Doctor said that does'nt look very promising. I also read on the internet that you usually can't see a heart beat on a sonogram until 7 weeks. Could I be further along? The doctor initially thought that my uterus felt about 11 or 12 weeks. Given all these obstacles is it probable that I not miscarry. I have 3 children and a stepdaughter, and certainly did'nt plan on having anymore.....but now I am a little excited and definitely worried... so many different emotions. I go back a week from tomorrow for another sono. I am also concerned about my lower back pain. I am also 39.
