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