I never put two and two together... but starting thinking that my mirena's hormones may be causing my issues. I had the mirena inserted a yr ago when I had the copper IUD removed. I told my OB/GYN that I was scared of the pill after trying it in college. Hormone-based birth control doesn't seem to work well for my family. She said it was a tiny dose and wouldn't get in the bloodstream so I shouldn't see side effects. HOWEVER, over the last year I have struggled with my weight. I have always been reallllly lucky. I am 5'8 and weigh about 135 without trying too hard. I have a high metabolism. But, I've started to feel pudgy last few months so have really tightened up my diet. I thought it was because I am getting older (29)... As far as exercise, I used to be very active (mini-triathlons, 5Ks, sports etc.) but haven't felt like working out this year. Just can't get motivated. Today I was working with a personal trainer. We checked my records from January and I have gained 7 lbs!!! This is after I have really firmed up my diet. I have stopped eating carbs at night and trying to not eat after 7ish. In the past, this would really help my body look its best after a week or two. But, these last few months hasn't seemed to help me at all... Maybe it's the MIRENA?! In addition, my cycle is about 7 days lator than it used to be. However, I still have the PMS symptoms I used to the week before my period but now they last forever! They start on the 20th and last until my period starts on the 7th!!! I get so irritable with my 5 yr old its ridiculous. It's not fair to her or my husband. I just wanted to share, that even with an athletic body type and a ridiculously high metabolism I am struggling. 2 yrs. ago I could eat 2300 calories w/out exercise, 2500 or more if working out that day. I used to eat as much as my 6'2 husband.
