Hi, I am roughly 5 weeks pregnant after trying for 2 years. Last week I experienced severe pain and went to A&E where they tested my HCG level - it came back at 74. Two days later it was 208, then 308, then 429. I have had light spotting on and off for a week now. The hospital won't say anything other than we now have to have the blood test repeated in 5 days and a scan. I am driving myself crazy with worry as the level isn't doubling every 48 hours - has anyone ever experienced this or can give me some answers - I just want to know if my baby stands a chance of survival.
