Could Weight Gain And Severe Mood Swings Be Due To Plan B?

Hi, I had taken Plan B in march of 2014, After I had put on a few pounds, got bad acne, and was a crazy person for at least 3-6 months, some systems went away first. I didn t know what was causing this to happen, until In July 2014 I was very stupid and had to take plan B, 2 times in 2 weeks, when I was reading on it to make sure it was ok to take the second time I had come across the idea that it was caused from the plan B. This time around I didn t have a choice but to take it again. I had a really bad period then, didn t have one for 4 months. I put on even more pounds this time, but didn t experience mood issues. I was working out an hour of cardio a day, and even cut back to 1,500 calories a day to try to lose the weight but it just kept on coming. I m very tall and until I took this pill I was eating about 3,000-5,000 calories aday, and was a 30bust,23waist,and 34 hip. I m 21 years old, and I have lost the 15 pounds that I put on after the pill. and am still losing about 0.4 pounds a day. I workout for about 20 mins a day and am eating from 1,500-2,000 calories a day. My mother told me she has never been aboul to take artificial hormones, because of the hormones our body s have and don t have. My question is how long would it take for your hormones to even out again after taking plan B 2 times in 2 weeks, And will they rebalance back to the way they where before? the last two periods I had where on track, but still a little light for what they used to be. Not to light tho, still more then most people experience. And what is a way to rebalance them out if they are not already back to normal?
