Well yesterday wasn't much help to us either!! My levels have gone up again to over 600 (2 days prior they were 470 so not quite doubling). I have to go back on Monday for another blood test. They are still unable to see anything on the scans. I have a feeling I'm a few weeks earlier than what they think. I didn't miss a period, but my doctor is going off the one prior to my last, which would make me 7-8 weeks, but I think I am personally going onto 5. This is so frustrating!! It would explain why they are unable to see anything on the scans. They keep talking about ectopic but they can't even see anything in my tubes either yet!! Which would also make sense if I am as early as I think. I have still been spotting, but it's only once a day and it's not red, it's a watery brown (tmi). I just want to know what is happening!!! Argh!! Has anyone else been through this?? Pregnancy of unknown location.
