a result of only 20 doesn't mean much at all. you've had a BT a week after when they THOUGHT you would ovulate based on taking the clomid, but clomid is notorious for making people ovulate later and extending cycles. so it's highly possible that you simply ovulated later than anticipated, so you were only a few DPO, and your Dr is playing it safe by reminding you that early miscarriage is, unfortunately, far too common.

hope is the one thing that you have ultimate control over - and you need to remain positive through your pregnancy
