Hi I have been pretty irregular and it seems my periods have been 34-38 days and this time its 40 days today and no period can I be pregnant? I have been having cramps once in a while felt bloated two days ago and very tired fatigue and now sometimes cramps once in a while and was wondering If I can be pregnant did a test 3 or 4 days ago came out negative ... any ideas of my possibilities of being pregnant?
