Only recently started trying to conceive. My periods are pretty regular at 28 days and have never been missed. During my last cycle I took a test 4 days early that came up positive and then around the time my period was due i took another to find it was negative. I figured it was a chemical pregnancy and my own fault for testing early!my period has been completely missed and I'm technically now on day 47 and still nothing! I've had one other faint positive a week ago but every other test has been negative. Has anybody else experienced this when they first started trying? Is it psychological? I've recently started taking folic acid and have heard that can have an effect on the length of the cycle, could this have anything to do with it?
