Hello, and i hope I can help you today. First of all, it is not normal to not menstruate for a year unless you were breastfeeding. If you turn out not to be pregnant, you really should see a local physician and have a full hormonal evaluation to see why you are not menstruating. Pregnancy symptoms vary widely between women, and many of the symptoms we usually associate with pregnancy like bloating, breast tenderness, nausea, fatigue, spotting and mood changes can happen in cases of hormonal imbalances as well as pregnancy. The most common (and reliable) sign of pregnancy is missing your period, however in your case, you cannot use that as a guide. A pregnancy test will only become positive at least 3 weeks after conception. So at this time I suggest you wait three weeks and then perform a urine pregnancy test. I hope I was able to adequately answer your question today and that my advice was helpful. Best wishes, Dr. Brown
