I have an early scan at 6+3 (tomorrow) having had 3 days of dark brown spotting last weekend. I am on progesterone supplements and started these 2 days before the spotting kicked in but this has now stopped. So far I have no symptoms that I can tell. Perhaps tiredness and the odd sleepless night but nothing obvious. I'm concerned I'm going to get to the scan and find out the progesterone is masking that it's all over. If it's all ok, would I expect to see a heartbeat at 6+3??
