Miscarriage?

Hi ladies,

So here is my story...

On march 16th i did bloodwork my levels were at 420 i thought i was only 3 weeks and 5 days.. doctor told me to do another bloodwork asap and a ultrasound in one week since my levels were very low. I repeat the bloodwork on march 23rd got my results 2 days ago and within a week my levels when up! Good news i know...

Now here is the thing.. i have been spotting brown lately it finally stopped.. (Thank god) but i did an ultrasound yesterday me thinking i will be 6 weeks and 3 days.. the Tech said it looked like a pregnancy but unfortunately its too early to measure anything.. she did saw something she said..

Now im sitting here thinking how could my levels be at 4000 a week ago and now she is not able to measure anything?

Anyone experienced the same thing? I typed fast as if i was emotional and nervous.

And ooh Yeah do feel little cramps here and there but nothing big...

Please share your experiences!
