I had two cycles last month, in a period of two weeks. SO of course my cycle is going to be thrown off. However, I'm now 21 days late and I've taken two different tests which both came out negative. I'm skeptical though because I have all the symptoms of being pregnant. At least, the common symptoms I'm used to. (I've been pregnant twice and both times I misscarried) I'm exhausted all the time and I'm sleeping 15 hours at a time. I'm hungry and nothing satisfies! I have ZERO interest in sex and my mood is either normal or I'm depressed and crying. I don't know what's going on with my body!
