Am I gaining weight by eating 1500 kcal pr. day??

Hi guys.
I'm a 20 year old girl, who weights 82 kg and i'm 165 cm tall.
I've lost 30 kg over the last year, so my body has kinda come to a stop, and it's getting really hard for me to lose weight now, but I still have a lot to lose.

MFP tells me to eat 1330 kcal pr. day, but I'm having a REALLY hard time staying within my daily limit, and I usually end up eating for at least 1500-1700 kcal pr. day. I haven't lost weight in a couple of weeks, and I've even put on a bit.

Do I really gain weight by eating only 1500(+/-) kcal pr. day??
