You nurse sounds like she has been very good. I haven't seen anyone. No one wanted to take my blood which is a shame cos I would have liked to hear it from someone in authority that I am deffinatetly not imagining all my HPT being positive! LOL
And while I am whinging, I wish they were doing my scan as early as yours I am going to be 8 and half weeks pregnant by then and every day seems like an age.
In answer to how pregnant are we, let me try and explain again. It so confussing isn't it cos books often take about the embryo's first week and then in the next breath they say at six weeks, when they actually mean the embryo's fourth week.
So ignore when your period was. It wasn't a real period it was a bleed due to down regs.
count back 14 days from Egg Transfere Saturday 3rd March that would have been the first day of your natural period and Sat 3rd - Sat 10th is counted at week one of being pregnant even though technically we weren't yet.
Sat 10th - Sat 17th is week two with fertilisation offcially happening on the 16th
Sat 17th - tues 20th embryo should be traveling down tubes but of course ours were already in the womb.
Wed 21st - Fri 23rd the embryo now a blastocyst implants and hatches out conecting with our blood supply.
Sat 24th we are now 3 weeks pregnant
Sat 24th -Fri 30th by the end of this week "a dark mark appears on the.back of the embry marking out the spinal cord."
Sat 31st we are now 4 weeks pregnant
I might be a day out but I think thats roughly correct.
During this week week five ivillage says "our babies hearts begin to beat all their major organs are under development facial features start to form and the spinal cord fuses this week. buds appear that will soon be legs and arms. the embryo is now 1.5 to 2.5 mm long! This could be why you are so tired" and hungry!
No spotting yesterday thank God!!!! cramps on and off but no wonder reading the above! Very hungry had to eat at 11 last night not like me.

If i have got any of the above wrong I apologise xxx
