20 1/2 week checkup

Hello everyone!  I went in for a checkup visit this afternoon, and everything looks good.  They are 13.5 and 14 ounces, very active.  Cervix is at 3.5 cm.  One measures right in the 20 week range, and the other at 21 weeks.  (I'll be 21 weeks on Thursday.)  They were both moving so much they had to be chased around to get their heart rates! ha!  (Which were 135 and 152) I can see already they are going to be a handful!   Ah, those girls...it's gonna be so much fun!  (That is, after the sleep deprivation, exhaustion, etc...) lolThe past few weeks I've been feeling very good - except for some heartburn every now and then.  Usually if I'm careful with eating habits I can avoid most of that too.Hope you are all doing well!
