Hi, I got pregnant with the IUD in situ, I had it removed as soon as the blood test showed positive. I had a tetr blood test and the numbers doubled from 640 to 1440. I had my first ultrasound last week, and it showed a baby sac, and good heartbeat, but also evidence of retro-decidual collection in front of the sac about 1.5 cc . The cervical canal is closed, and i experienced no bleeding except for a light brownish discharge only once after intercourse. I don t know what does that mean, and should I take any medications? because I actually feel it s better to leave things as they are without the interference of medication. Am I right or is my case really risky and need medication? Also should I quit my job and stay home at bedrest? I am 7 weeks pregnant now
