I'm feeling so swollen...5 weeks post op!

Hi everyone. I was wondering if ANYONE out there had edema in their feet and or legs weeks after surgery. I haven't had any IV fluids for almost 2 weeks now, and my feet/ankles/legs are swollen.  I can still walk, exercise on them which is great, but it seems ever since I had IV fluids 2 weeks ago I'm swollen.  Gained 7 lbs water weight last week, now 3 came off, but legs and tummy seem to be retaining some water. 

What at may be part of the problem is that I am due for my period in the next few days. I get that about my tummy feeling water logged.. But I feel like I'm gaining weight and I'm just a bit irritated about it honestly. I get I'm PMSing, but for 2 weeks my legs and tummy are swollen? I hope this isn't some new PMS symptom of mine! Lol

Sorry just venting.  

I learn that elevating my legs on the wall (laying flat on the floor) and gently moving my legs really help if i get any water retention....
