Thanks for all your kind replies.
I spoke to my midwife today to tell them what happened at the private scan. Given the date of my last bleed on the 12th april they agree I should be 8 weeks and cannot understand why I am measuring 5, they said it does not sound good. They will arrange a scan for me at the end of next week so at least I don't have to wait 2 weeks now. They will see if it has grown any from the private scan and if it is viable.
Feel really deflated. Was so excited about this pregnancy especially since the chemical we had last time. I hope I have severely muddled up the dates or by some freak of nature occurance my dates were all messed up from the chemical pregnancy ruining my cycle. I don't have any symptoms of pregnancy though which makes me fearful.
I have been taking pregnancy tests all throughout this one though, and the result has been getting stronger to the point of it showing positive after 2 seconds and then it gets as strong as the control line. Surely it would have started to drop if it stopped growing 2 - 3 weeks ago.
It is all so confusing, just got to sit and wait now. x
