Another one down...i think???

So I came to the conclusion today that I really have no idea how far along I am.  Not only because Im basing it off of a date when I definitly did not conceive but I have no idea what counts as weeks being done.  If I'm 6 weeks, 2 days pregnant...does that mean I'm 6 weeks?  I would say I'm 7 because I finished 6 full weeks...right?  I mean would you say you are only 8 months pregnant when you deliver because you didn't actually finish the full 9th month?  Or do we say 9 months because we are actually pregnant for 10?  ugh this is making my head hurt!!

So far I've only received conflicting advice.  I have an app on my phone that says I'm "in" my 7th week and that during this next week the baby will start to grow fingers and a brain.  But babycenter.com says I'm 6 weeks pregnant and repeats what I posted last week about milestones....

So I guess I'll say I finished 6 weeks of being pregnant and thats it...I have something in my stomach that may have fingers or maybe its still just beginning to have a nose, mouth and ears?  And its either the size of a lentil or a bluebery. In anycase something is in there (although sometimes I second guess myself because I lack a lot of the so called "common" symptoms) and its growing.

So heres to the next week...would that be week 7 or 8???

oh yah and GO PACK GO!
