Gain an Inch

So back in February I got a new doctor, and since I've never gotten my blood checked I figured it might be a good time. Get a genealogy test done and blood work, just to make sure I'm all healthy and that junk.
Well low and behold I'm not healthy. I apparently have a Vitamin D deficiency (as everyone else in Western NY does) and I have a calcium deficiency along with a inactive Parathyroid. So my doc told me that I need to take these calcium supplements twice daily. I don't get why, I already take a multivitamin that is supposed to supply me with 200% my DV of calcium and vitamin D. So I'm thinking that something else is screwed up, like my parathyroids really not working.
Anyways I started taking these pills. Along with this I was working out twice a week doing kickboxing and step aerobics. With in 3 weeks, I gained 6lbs! And not gradually either. It was literally over a 2 day period.
Really! WTF. I don't know where it is on me cause my body hasn't changed but it's pissing me off. I watch what I eat now, and I run daily and I still do kickboxing, and it's still there. I'm thinking maybe it's just muscle that has accumulated but I doubt it. I'm just pissed. I've weighed the same amount for the past 6 years...6 YEARS! I've been healthy and active and always being careful not to overindulge myself.
It's just a self confidence thing. I don't like know that it just shot up there and I don't know why. Is it cause of the damn pills? Cause of muscle? What? I want to know. I see my doctor next month and I'm going to bring it up.
So yea I needed to vent my upset behavior about gaining 6 pounds over night.

yup I'm a temperamental woman.
