Well I have a bit of an update. My doctor sent me for an ultrasound the Monday after all this started but I had to wait til all the public holidays were over. I had a little bit more brown mucus over the Christmas weekend but no cramping. Finally got my ultrasound yesterday when I should've been 7 weeks 3 days.

They did an abdominal ultrasound & only found a gestational sac measuring at 5 weeks 4 days. The sonographer said it looked good and had implanted well but I was crying saying I was sure of my dates. She told me not to worry & stranger things happen but I was still very upset yesterday.
I still have some pregnancy symptoms so don't know what to think. I asked for HCG levels to be done, had one today, will have another tomorrow & the last on Tuesday. Besides that I'm booked in for another ultrasound in 2 more weeks. It's such a long time away but at least the HCG will give us an idea of what to expect in the meantime.

I feel like I'm in limbo - I thought I'd have an answer after 10 days of waiting & here I am still waiting. I want this baby so much
I am so sorry you are going throught his CM

I was just reading through allthis and suddenly had a thought and I may be way off but thought its best to cover everything so I should mention it. You said above that the day when you got the results back from the U/S that you thought you were 7wks 3 days but the doctor told you the sac was only measuring 5wks 4days (13 days behind your dates). Could it be that the sac was measuring 5wks 4 days on the day of the ultrasound not the day you got the results back? I dont know if I am making sense or not but if I am right, you wouldnt be as far out as you think. It might be something worth clarifying with the doctor.

I am praying everything will be okay for your little one
