I will start by saying I haven't been with a man in 4 12 yrs. But I recently got married and my husband and I are trying to conceive. My cycle is usually pretty normal. I can bet on it an win. But since we are trying to have a baby, I made sure that we were together during my fertile and ovulating days for pretty much for a week we were trying to conceive everyday. But I got my cycle early. I had 2 cycles in January. The second one was a week and a day early, but was also a day shorter and a lighter then usual, but still a period. Could it be that my cycle is changing or just reacting to the sperm since it has been 4 1/2 yrs.
