Nobody really seems sure how far along I am.. My lmp was just over 6 weeks ago so am I right in saying I could be as early as three or four weeks? Took positive pregnancy tests (about three) and I've had little bits of cramping here and there. Started spotting very tiny bits of brown discharge (sorry tmi) a couple of days ago but only tiny bits when I wiped. It lasted all of about an evening and its come on last night and today too. Starting to worry me even though its just a bit. Had my hcg checked last Monday and Wednesday and they said they were 416 on the Monday and 700 on Wednesday. They seem quite low for me and I'm really anxious. The mood swings aren't helping. Can anybody share any input or advice?
