I went of bc - a generic form of ortho-tri lo - in July 2013. My periods were very irregular after that (before I ever went on bc I was always regular). I just started my May period and I had one in Feb, March and April. I'm fairly certain I ovulated last month. I'm 23 and a little overweight also. My doctor has also told me that it takes up to a year for the pill to be fully out of my system. My questions is, after your periods regulated, about how long did it take for you other ladies to conceive? TIA!
