Stuck!

Ok so I'm 5'2 150-155lbs. I started last May at 180lbs. I lost 30lbs by aug last year. Ever since I haven't lost anything. I've maintained or even gained! I run 15mins a day 4 times a week and lift pretty heavy 4 days. Then I do one- two 30-45 min spinning classes days I'm not lifting. I eat pretty clean (see diary) except for a few days I cave a little. Especially working restaurant weekends /: struggle. My thing is eating 1200-1400 calories a day I should be losing... And I don't believe it's muscle gain because you can't gain muscle in a deficit! I'm ready to meet my goal of 130-125lbs! It's so frustrating! Has anyone had this problem?! I'm debating even going to see a doctor because I think after almost a year my body should be cooperating and losing weight again! I don't believe in starvation mode because eventually your body comes down to cal burn to cals in! I've even recently changed my fitness pal to lose only 1lb a week. It upped my calories to 1400 cal a day but all I've seen is a gain! Ugh so frustrating! ????????
