Hellooooo Morning Sickness and Defining Weeks

Guess who came for a visit this morning?  Good old make me pray to the porcelain goddess.  And first thing this morning BEFORE I had a chance to eat or drink anything.  Helllllooooo Dry heaves..BLECH.

OK now seriously, why don't we have Internet code names for things like Morning Sickness? I mean come on we have Aunt Flo and Baby Dance and all sorts for the infertility discussions, but none for the pregnancy ones?  Or am I just so new to this that I don't know them yet...HRMMM that is a possibility I guess.

Totally switching topics, I got an interesting call yesterday from my sister (who reads my blog) and she and my dad (who also reads) were totally confused as to how I could be 4 1/2 weeks pregnant.  I just had the transfer 2 weeks ago, how was that possible?  I realized that I have quite a few folks who read my blog that are not well versed with infertility and pregnancy, and this was actually confusing for me at first too.

The human gestation period is actually 40 weeks, not the 9 months commonly thought, and is commonly calculated from the first day of the Last Menstrual Period (LMP).  Most women area already considered 4 weeks pregnant (28 days from their LMP) when they find out that they are pregnant and only have 36 weeks to go (hence the 9 month idea).  The idea is that the egg is starting to develop on Day 1 of the LMP, so that is the official first day of pregnancy, if it happens.  All of this assumes that the woman has a "normal" 28 day cycle and ovulates on day 14.  Since we all know that "normal" is very rare, this is why calendar pregnancy duration and measured pregnancy duration (via ultrasound) can vary by up to a week.  For us, we KNOW conception occurred on July 29th (retrieval day), so I know exactly where I should be time wise.  Measuring ahead or behind will be an indication of how well the baby(ies) are developing.

Medical lecture over.  I hope you took notes, there will be a test next week :-)
