Leaving My Job? And 19 Weeks

I have almost completely decided to leave this job after maternity leave.  I asked HR if there were any consequences if I decided not to come back, and here is what they told me:

"What I have found out is if you do not return to work for reasons other than a serious health condition for yourself or a family member, the company may require you to reimburse the total costs associated with the leave.  Which means they could request the portion that [my employer] pays for your insurance to be reimbursed to them for your leave period.  Any STD (short-term disability) that was paid out, would need to be reimbursed to the company as well.   Basically they would go back to the last day you worked prior to the leave and use that as your term date.  

If you were to come back let’s say for a week, none of the above would apply.

Let me know if you need any additional information."

So, I guess the plan is to take my 12 weeks, come back for a week or two, and then get the heck out of dodge.  The only question is, when do I give notice?  Is there a possibility that they'll ask me to NOT come back for that week if I'm just going to leave again?  What to do?! If anyone has any advice or insight, I would appreciate it!

Here are the weekly stuffs, feel free to skip right on by!

* Belly - Definitely popping out now, and starting to look very round.  I've got some skin just hanging there looking gross at the bottom of my "gut".  I really hate it, and can't enjoy looking at myself uncovered.

* Weight gain - They didn't put me on the scales at my last appointment, so I'm not sure.

* Symptoms - Have I mentioned that I'm so tired!  I'm also noticing a lot more round ligament pain this week.

* Cravings/Aversions -  Sweets and Chinese food, still.  Especially strawberry pop tarts, which then make me feel super yucky!  I can't seem to resist, though.

* Clothes - No change, I'm completely on maternity pants or regular pants and a Bella Band.  My regular tops are still fitting ok.

* Movement - I am definitely feeling her move more often!  It is the most amazing thing in the world!

* Feelings on gender - We're having a girl!  It still feels so surreal to be referring to my baby as "her", "she", and "my daughter"!  <3

* Meds - Morning:  Regular multivitamin, 2000 ui Vitamin D, Clari.ten 10 mg, 1600 mcg Folic Acid, 2 puffs of Symbi.cort (new change from Advair).  Mid-day:  600 iu Calcium x2.  Evening:  Prenatal, 800 mcg Folic Acid, Rhino.cort (new change from Flonase), Symbi.cort, 450 mg DHA, 30 mg Hydrocortisone.  New:  I had one-dose Difl.ucan to clear up a yeast infection.

* Mood - The only thing that seems to be getting me down is work.

* What I miss - I went to a wine and art festival over the weekend with my husband, mother-in-law, and a friend.  I enjoyed the food and the art, but I missed the wine tasting!  It's worth it, though.

* Appointments - My next regular OB appointment is on the 22nd, and my next MFM appointment (with US and cervix/placenta) is Nov. 5th.

* Medical concerns - Nutrition/calories, vitamin levels, CAH, Placenta Previa (sigh).

* Coming up - Starting to look at nursery themes!
