I started spotting since 5w2d..At 6w1d my hcg was 11,757...which has been doubling normally.. But the Ultrasound showed a gestational sac of 7mm and a yolk sac of 1mm which is less i think.. considering I m 6w1d and the sac size has been the same since 5w4d..but this may be because I have no corpus luteum to secrete progesterone and also I have a 4mm SCH..My doctor said that is what is causing the spotting. I’m on complete bed rest for now and also on progesterone injections .. my next appointment will be next week on 7th December. Doctor is hoping to see a heartbeat and reduced bleeding near the sac. I’m on 50-50% chance of having a successful pregnancy or miscarriage.. any success stories???
