5lb in April

Hello. Looking for some suggestions. I started MFP Feb 9 and I've lost 10lb so far. I'm hoping to lose 5lb this month for upcoming vacation. I've been losing weight at this rate but for the past few weeks, I've stalled a little. I weigh every solid and measure everything I eat. I work out at least 30 minutes 6 days a week. Mainly circuit training (Ripped in 30) with 1 or 2 days of jogging for 20 to 30 minutes. I try to stay around 1400 calories a day. I've been stuck at the same weight for the past 2 weeks. Any suggestions what I should try to rev up the weight loss this month a little? I have an open diary, so please feel free to make any suggestions on that too.
THANKS
