Weight Loss

So on March 22nd I weighed 175 and today I weigh 166!
That's 9lbs in two monthes! I'm used to losing wieght quicker but I am also used to going to the gym 4-5 times a week and doing 10 minute abs everyday. Now I'm lucky if I get to the gym 3 times a week. My brother's wedding is July 15th. Do you think that I can reach the 155 mark by then?
