I had IUI on the 24th June so i'm not sure how far along I am. Will they go on LMP or date of IUI? I've had 3 lots of really bad pains recently and am worried about another mc.. My first hcg level was 59, two days later was 393, this was around 2 weeks ago. I went for blood tests yesterday and my levels are now 9,787. Today I went for an early scan and the sac was empty and a cyst was seen on my left ovary. They also said the size of the sac is around 5 weeks. If they go on date of IUI, then i'm not quite 5 weeks, so it sounds right that the sac measures 5 weeks. How can my levels be so high? Yet an empty sac? Is this another mc? The hospital can't rule out eptopic but surely I would have bleeding and severe pain on a regular basis.. Perhaps it's a slow starter or i'm not as far along as the hospital think? I haven't been back to the clinic where I had the IUI done so perhaps the hospital is wrong and when I go back tomorrow there will be a foetal pole.. My boobs are still sore, starting to feel sick and very tired come the afternoon. I've been taking cyclogest until recently. Any help gratefully received
