21 weeks!

So, Oct 27, yesterday, we had our ultrasound.  I was supposed to be 19 wks 4 days but the ultrasound said i was 21 weeks-YAY!  (skipping 2 weeks is good!)  Dad found out what the sex is and told big sister, Aunt Lan and grandma!  I decided not to find out but I think it's a boy!  The scary part was that they told me my cervix is short.  Went to the doctor today and he said he would show the ultrasound to Dr. Wong, the perinatologist.  They will let me know if I need to get a cerclage or if we are just gonna monitor it.  Either way, I will probably be having u/s every week to two weeks.  I'm not worrying, though, things will all be okay!

18 weeks

Dr. appt at 14 weeks and we had another ultrasound since I was worried-needlessly.  Everything looks good!  Dr. L told me to take magnesium oxide 500mg and riboflavin -50 mg for my headaches.  Started the magnesium right away and it seemed to help a bit.  Just got the riboflavin.  Headaches are almost gone.  At 16 weeks my students noticed my belly was bigger, measured it at 39 inches-it was 36 the day before.  One week later it was 41 inches.  Now, at almost 19 weeks, it is 42.  I've never thought to do that before, it's kinda fun!
Milk is still low but Afton is still nursing (and cutting molar-ouch!).  I'm not getting much sleep which doesn't help at all.  I also decided to become a La Leche League leader since we don't have one around here.  I think it will take me about a year.  I'm excited! 
Go back for ultrasound in a week!  Maybe know sex then?
