Today Is Thursday...

And it's a big day!

Today was the day we had our first beta!  I received a call from the clinic and our beta numbers are:

199!

Let me explain a little bit about what those numbers mean.  It doesn't take much hCG, to confirm a positive pregnancy.  Typically a singleton pregnancy produces beta numbers around 100.  A twin pregnancy is usually around 200.  Visit this site for charts on Betas.   BetaBase.info   When you look at these charts, we are currently 14 Days Past Ovulation. I will go back to the clinic on Monday for a second beta, and again on Thursday for a 3rd and final beta.  We are looking for our numbers to at least double each time. 

The clinic's thoughts were that our numbers definitely support a twin pregnancy at this point, but obviously, there are no guarantees until you see those 2 beautiful hearts beating on the first ultrasound.  Our first ultrasound is scheduled for April 21st!  I am feeling so excited....so grateful....

Also, today marks the day that we are officially 4 weeks pregnant!  What?! How can that be you ask?  Let me run it down for you.  Pregnancy lasts approximately 40 weeks.  However, those weeks commence from the date of a woman's last period.  For most women this is about 2 weeks before conception.  Conception for us occurred on Thursday, March 17th.  We transferred 5 days later on the 22nd.  So 2 days after transfer, we were technically 3 weeks pregnant!  Crazy, right???  Well here are some additional crazy facts for you on this fine Thursday...

• The sex of the babies has already been determined.
• The embryos have now burrowed into my lining.
• The placenta is continuing to form.
• The first nerve cells are beginning to develop.
• The basic structure of what will become the digestive system, blood vessels and lungs are outlined.
• The spine, muscles and bones are already starting to form.
• The evolving neural tube will eventually become the central nervous system.

All I have to say is:  NO WONDER I AM SO TIRED!!!  :-)
