Why am I having more frequent period?

I've lost about 70 lbs over the ending 10 months. I had my gallbladder removed concluding August. Before losing weight, I be on about a 30 - 35 afternoon cycle. The last few months, it's be every 27 - 28 days. Last month, it was 26 days. Today I'm starting at lone 21 days! I'm 37 years old and enjoy one 17-year-old daughter. I have never have any surgeries to my reproductive organs, not even my tubes tied. I'm married, but the only entry that's different is that we've been more live lately (since I lost so much weight). Any ideas?
