Need Help! What am I doing wrong?!

I am sure this has been posted a 100 times but instead of taking the time to search (not feeling motivated today) I thought I would ask the experts!! :wink:

Quick background I am 5'6 187pds (as of today). My highest weight was 215ish and last year I lost my first intial 30pds. I weighed 183 in April and then gained about 10pds back from July/Aug 2012- December 2012. Since January 1st I have been back on the band wagon and trying to get to my goal of 145. In the month of January I have been slowly getting my eating under control and then starting February I have incorporated exercising. Here is my deal:

I weighed 186.4 Sunday 2/3 one week later I weighed 184.2 on 2/10 since then I haven't lost a SINGLE pound and I keep gaining and losing the same 3 pds!!! I have yet to see 184 again and on average I am about 186 consistently for days (I know I know I am not supposed to weigh myself everyday). For the past 2 weeks I have been working out 4 times a week, an hour each time and burning about 675-1000 cals each sesssion. Last week I started going to the gym and focusing on cardio. I have MFP set to lose 1 pd per week and it has me eating 1480 cals a day. I usually eat about 200-300 of my exercise cals back and NEVER let my NET go under 1000-1100. I drink at least 8 glasses water.

Today was my weigh in day and big shocker I am STILL up the same 3 stupid pds, 1 stupid 87 I weighed today.:huh: What gives?!?!

PS.. I have noticed I am retaining water lately, my ankles and legs are always swollen but pretty much down by the morning. My first goal is 13 weeks away, I wanted to be 165 and I am thinkin I am not going to make it :sad:

Any help would be GREATLY appreciated!!! :flowerforyou:
